1.1.1 Development Trend of Network Management

With the development of IT and IP technology and the convergence of telecommunications, IT,

media, and electronic industries, the telecommunications industry has witnessed tremendous

growth. The broadband services and mobile services have become the mainstream services in

telecommunications networks.

All-IP architecture and fixed-mobile convergence (FMC) are the network development goals

for the next three to five years, during which the market orientations and business modes of

telecom carriers will vary accordingly. The development of all-IP architecture is the leading

factor in the transition from the existing vertical network that is divided by technology and

service to the flattened horizontal network. Improving user experience, lowering operation

expenditure (OPEX), and improving efficiency are the driving forces for FMC.

Network convergence requires network management to be consolidated. To be oriented to the

future network trend, the iManager U2000 that is the integrated network management system

(NMS) combines all-IP and FMC, and manages carrier equipment and access equipment in a

centralized manner. The U2000 can perform not only integrated management of multi-domain

equipment but also integrated management at the network element (NE) and network layers.

The U2000 has revolutionized the layer-based management mode to meet the management

requirements in the transition from the existing vertical network to the flattened horizontal

network.

The integrated NMS U2000 aims to minimize operation and maintenance (O&M) costs for

customers and to bring more network value. The U2000 is based on the design of distributed

software architecture, and supports the new generation advanced telecom computing

architecture (ATCA) hardware platform. In addition, the super network management

capability and modular software architecture of the U2000 that shapes the development trend

in the future network management make the U2000 a leading all-IP and FMC management

solution.

1.1.2 Product Orientation

The U2000 is the major and future-oriented network management product and solution in

Huawei.

The U2000 is an integrated management platform for all equipment in the Huawei. It can

manage transport equipment, access equipment, and IP equipment (including routers, security

equipment, and Metro Ethernet equipment) in a centralized manner. The U2000 is designed as

the management system for Huawei equipment. With powerful management functions at the

NE and network layers, the U2000 is the major and future-oriented network management

product and solution in Huawei.

In the TMN hierarchy, the U2000 is located between the element management layer and

network management layer, and supports all functions of the NE and network layers. Figure

1-1 shows the network position of the U2000.

Multiple Operating Systems

The U2000 is a stand-alone application that can be installed on different operating systems

and databases. Hence, multiple operating systems are compatible.

The U2000 is developed based on Huawei's integrated management application platform

(iMAP). It supports Sun workstations, PC servers, Sybase databases, Oracle databases, SQL

Server databases, and Solaris, Windows, and SuSE Linux operating systems. It provides

high-end solutions to large-scale networks and low-cost solutions to small and medium-scale

networks.

Modular Architecture

The U2000 uses a modular design to increase system flexibility.

By adopting the mature and widely-used C/S (Client/Server) architecture, the U2000

supports distributed and hierarchical database system, service processing system, and

foreground application system, and supports concurrent operations of multiple clients, to

meet the management requirements of complex and large-scale networks.





1-5

The U2000 uses an object-oriented, multiprocessing, modular, and componentized

architecture design. Hence, the degree of coupling of NE management components

decreases. In addition, different application processes are integrated into the system by

means of registry files. In this way, the U2000 has flexible expansion capabilities.

Stand-alone and distributed deployment of the U2000 increases the management

capability to a great extent.

The modular architecture of the U2000 meets the management requirements of products

in a single domain and the integrated management requirements of products across

domains.

2 Networking and Application

About This Chapter

The U2000 provides a centralized networkwide management solution to transport, IP, and

access networks. In addition, the U2000 provides standard external interfaces to integrate with

the operation support system (OSS), to meet the management requirements of large-scale

transport networks.

2.1 U2000 Deployment Mode

The U2000 supports the centralized and distributed deployment modes of servers.

2.2 Networking Scheme Introduction

The U2000 adopts the widely used C/S (Client/Server) model. In such a model, the client and

the server communicate through the LAN or wide area network (WAN). The U2000 server

communicates with its managed devices in inband or outband networking mode.

2.3 Application Scenario of the U2000 Management

This topic describes the typical application scenario of U2000 management.

2.1 U2000 Deployment Mode

The U2000 supports the centralized and distributed deployment modes of servers.

The U2000 uses the Client/Server architecture. Depends on the sizes of managed networks,

the U2000 supports the centralized and distributed deployment modes of servers.

To ensure the high availability of the system, the U2000 supports the HA system (Veritas hot

standby). The HA system (Veritas hot standby) can also be configured in the distributed mode.

The U2000 system contains management components for manageable equipment. The

components support multiple instances in the distributed mode.

2.1.1 Centralized Deployment of the Single-Server System

The U2000 supports centralized deployment of the single-server system on Windows, Solaris

or SUSE Linux OS, that is, there is only one U2000 server on which all management

components are installed and all processes run.

2.1.2 Distributed Deployment



Product Description



Issue 03 (2010-11-02)

The U2000 supports distributed deployment of the single-server system on SUSE Linux OS.

Slave servers can share the CPU usage and memory usage of the master server. In this manner,

the load is balanced.

2.1.3 Centralized Deployment of an HA System

The U2000 HA system (Veritas hot standby) supports the centralized deployment mode where

there is only one server on either the primary site or the secondary site.

2.1.4 Distributed Deployment of an HA System

The U2000 HA system (Veritas hot standby) on SUSE Linux OS supports the distributed

deployment mode where both the primary and secondary sites use distributed systems.

2.1.1 Centralized Deployment of the Single-Server System

The U2000 supports centralized deployment of the single-server system on Windows, Solaris

or SUSE Linux OS, that is, there is only one U2000 server on which all management

components are installed and all processes run.

The U2000 supports a networking scheme of a single server and multiple clients. In the

centralized deployment mode of the single-server system, there is only one U2000 server on

which all management components are installed and all processes run. See Figure 2-1.

Figure 2-1 Single-server mode

This type of networking is applicable to medium and small-scale networks.

2.1.2 Distributed Deployment

The U2000 supports distributed deployment of the single-server system on SUSE Linux OS.

Slave servers can share the CPU usage and memory usage of the master server. In this manner,

the load is balanced.

The U2000 supports a networking scheme of multiple servers and clients, as shown in Figure

2-2.





2-3

Figure 2-2 Distributed deployment mode

The management components for manageable equipment can be deployed on different servers

or on the same server.

Distributed system consists of the master server and slave server, which compose a site to

perform the U2000 server function.

The master server is the core of a distributed system. The database server and the core

subsystems of the U2000 are running on the master server.

The non-core subsystems of the U2000 (such as the management components for manageable

equipment) are running on the slave server. In this way, the CPU usage and the memory usage

of the master server are lowered, the load is balanced between the master and slave servers

and the management capability of the U2000 is increased.

In the distributed deployment mode, you can deploy all servers in only the same LAN.

2.1.3 Centralized Deployment of an HA System

The U2000 HA system (Veritas hot standby) supports the centralized deployment mode where

there is only one server on either the primary site or the secondary site.



Product Description



Issue 03 (2010-11-02)

The primary and secondary sites comprise an HA system. The data in different locations is

backed up through a network. When a fault occurs in the primary site, the system switches to

the secondary site so that network monitoring continues. Figure 2-3 shows the networking

diagram.

Figure 2-3 Centralized deployment of an HA system

2.1.4 Distributed Deployment of an HA System

The U2000 HA system (Veritas hot standby) on SUSE Linux OS supports the distributed

deployment mode where both the primary and secondary sites use distributed systems.

The primary and secondary sites comprise an HA system. The data in different locations is

backed up through a network. When a fault occurs in the primary site, the system switches to

the secondary site so that network monitoring continues. In the primary or secondary site,

master and slave servers are deployed in a distributed mode. The slave servers can share the

CPU usage and memory usage of the master server. In this manner, the load is balanced

between the master and slave servers. Figure 2-4 shows the networking diagram.

2.2 Networking Scheme Introduction

The U2000 adopts the widely used C/S (Client/Server) model. In such a model, the client and

the server communicate through the LAN or wide area network (WAN). The U2000 server

communicates with its managed devices in inband or outband networking mode.

2.2.1 Inband Networking Mode

In inband networking mode, the U2000 uses the service channels that are provided by the

managed devices to manage the devices on the network. The messages sent from the U2000

are transmitted through the service channels of the managed devices.

2.2.2 Outband Networking Mode

In outband networking mode, the U2000 uses the communication channels that are provided

by devices other than the managed devices to transmit messages for network management. In

normal cases, the management interface on the main processing unit or routing switch unit of

the managed device are used as the access interface.

2.2.1 Inband Networking Mode

In inband networking mode, the U2000 uses the service channels that are provided by the

managed devices to manage the devices on the network. The messages sent from the U2000

are transmitted through the service channels of the managed devices.

Figure 2-5 shows the inband networking diagram.

Managed Network

NMS

Networking Description

The devices managed by the U2000 are all connected to the managed network. The U2000

needs to be connected to only the nearby NE on the managed network. After configuring the

related routes, you can manage all the devices on the network.

The way of connecting the U2000 with the managed network depends on the distance

between the U2000 and its nearby NE. If the U2000 and its nearby IP devices are in the same

equipment room, you can use the LAN mode. If the U2000 and its nearby IP devices are far

from each other, you can use the private line mode. The private line mode is similar to the

outband networking mode.

Networking Advantages: This networking mode is flexible and cost-effective. It does not

need extra devices.

Networking Disadvantages: In the case of network failure, the communication channel

between the U2000 and its managed network is interrupted. As a result, the U2000

cannot maintain the managed network.

2.2.2 Outband Networking Mode

In outband networking mode, the U2000 uses the communication channels that are provided

by devices other than the managed devices to transmit messages for network management. In

normal cases, the management interface on the main processing unit or routing switch unit of

the managed device are used as the access interface.

In this mode, the U2000 can be connected to the managed devices in multiple ways. The

U2000 manages the devices within its management scope through the data communication

network (DCN).Figure 2-6 shows the outband networking mode.





2-7

Figure 2-6 Outband networking mode

Managed Network

NMS

DCN

Networking description

The devices managed by the U2000 are all connected to the managed network. The U2000

connects with the devices on the managed network through the DCN that is made up of other

devices. In this manner, the U2000 implements its management on the managed network and

devices.

Networking advantages: In outband networking mode, the U2000 is connected to its

managed devices through other devices. It is not connected to its managed devices

directly. Compared with the inband networking mode, this mode provides more reliable

device management channels. When a fault occurs on a managed device, the U2000 can

locate information about the faulty device in a timely manner and monitor this device in

real time.

Networking disadvantages: In outband networking mode, the U2000 manages its

managed devices through a maintenance channel that is independent of the service

channel. To provide such a maintenance channel, you need to build a network that is

made up of extra devices. Thus, the cost of constructing the network is high.

Service Deployment

Carrying multiple services is one of the most distinctive features of the Metro Ethernet.

Services such as the high-speed internet (HSI) service, IPTV, and voice over IP (VoIP) must

be established on logical channels.

The U2000 allows you to quickly establish specific logical channels on physical networks.

For example, you can quickly establish end-to-end MPLS LSP, MPLS TE, PW, and VPLS

logical channels through GUIs. You can verify the validity of services before deployment and

modify services after the logical channels are established.

The Metro Ethernet often carries heavy service traffic. To adapt to this feature, the U2000

provides the batch deployment function to accelerate the deployment process.

To ensure the reliability of key channels, you can configure protection protocols such as BFD,

VRRP, and MPLS OAM.

Login and Session Management

The functions of login and session management are described as follows:

The user can log in to the U2000 with an account. The user performs operations

according to the permissions assigned to the account.

If the client is not used for a period of time, the user can manually lock the client or set

the lock time to make the U2000 lock the client automatically. This prevents others from

performing operations illegitimately. If the client is locked out, you need to enter the user

password or use the administrator account to unlock the client.

The members of the administrator group have the permissions to monitor the session

information and log out of illegitimate users forcibly.



Product Description



Issue 03 (2010-11-02)

The U2000 can automatically detect and clear invalid sessions.

User and User Group Management

The functions of user and user group management are described as follows:

Creating a user account or user group. During user account creation, the user details,

owner group of the user, management domain, user permissions, and access control list

must be set. During user group creation, the user group details, management domain, and

user group permissions must be set.

Modifying the user or user group information, and deleting a user account or user group.

Adding a user to a user group. After addition, the user has the permissions of the user

group. A user can be added to multiple user groups. In this case, the user has the

permissions of the user groups besides those of the user.

Permission Management

User permissions are classified into management permissions and operation permissions.

Through permission assignment, user operations on the U2000 can be controlled.

Management permissions refer to the permissions that a user is given to manage the

specified equipment and its data, or the permissions that a user group is given to manage

the specified domains. In the topology view, the equipment or areas that cannot be

managed are invisible.

Operation permissions refer to the permissions that a user is given to perform operations.

If a user does not have the permissions to manage a type of equipment, the user does not

have the permissions to operate the equipment.

The functions of permission management are described as follows:

Adding or deleting user or user group permissions, and setting the management domain

of the user or user group.

Creating object sets. Managed objects are grouped into different object sets to facilitate

permission assignment.

Creating operation sets. Operation permissions are grouped into different operation sets

to facilitate permission assignment.

Modifying or deleting object sets or operation sets.

Assigning the permissions of a type set to the user. After that, the user has the

permissions to view and operate the devices whose type is consistent with the type set.

Security Policy Management

The functions of security policy management are described as follows:

The password policy is used to set the user password rules and password security

policies. The password rules involve the minimum password length of common users,

minimum password length of superusers, and maximum password length. The password

security policies involve the maximum number of password duplications with history

passwords, maximum password reservation period, minimum password reservation

period, and number of days ahead for notifying password expiration.

The account policy is used to set the minimum length of the user name, automatic

unlocking time, maximum number of login attempts, and timeout period at a login or

unlocking failure.





4-5

Access Control List

The Access Control List (ACL) is a secure access control mechanism. It restricts user access

to the server by allowing only the clients with specified IP addresses.

ACL can effectively control the client IP addresses from which users can log in to the U2000.

In this case, even if the user account and password are obtained by illegal users, these users

cannot log in to the U2000. Thus, the security of the U2000 is improved.

4.2 Topology Management

In topology management, the managed NEs and their connections are displayed in a topology

view. The managed NEs are displayed and managed in subnets and views. You can monitor

the operating status of the entire network in real time by browsing the topology view.

U2000 provides the Physical Root, Clock View, IP View, Tunnel View, and Custom View.

Therefore, you can view the required information in different views and also monitor and

learn the operating status of the entire network.

Topology View and Its Functions

The topology view of the U2000 consists of a navigation tree on the left and a view on the

right. The navigation tree directly shows the network hierarchy. Meanwhile, the view displays

the objects at different coordinates in the background map, which offers an intuitive view on

the deployment of objects.

Figure 4-3 shows the functions provided in the topology view of the U2000.

Figure 4-3 Topology view and its functions



Product Description



Issue 03 (2010-11-02)

Adjustable topology view: The view can be zoomed in or out so that you can view the

objects clearly.

Bird's eye view: You can see the position of the current topological window in the entire

view.

Network-wide NE statistics collection: You can collect statistics on the number of NE

types and the number of NEs of each type in the entire network.

Filter tree: You can filter all the NEs to display only the required NEs quickly.

Status bar: It displays the information such as the current status, current login user, IP

address of the server that is connected currently, and current operation result.

Topology view: A GUI in the U2000, which reflects the network structure. This GUI

shows various physical and logical entities of the network and provides the entrances of

various operations.

Alarm Display In the Topology View

In the topology view of the U2000, alarms are displayed in different colors to indicate

different status of the submaps and NEs. The alarms in the topology view are displayed by

two methods: color-coded display and small icon display. The default method is the small

icon display, as shown in Figure 4-4.

Figure 4-4 Alarm display in the topology view

The display of topology alarms on the U2000 has the following features:

The color of a topological node indicates the polling status (such as normal, unknown, or

offline) and the alarm status of the monitored NE.

When an NE generates multiple fault alarms at different severities, the corresponding

topological node is displayed in the color/iron that indicates the highest alarm severity of

these alarms.

When multiple nodes in a subnet generate fault alarms, the subnet is displayed in the

color/iron that indicates the highest alarm severity of these alarms.

You can query the current alarms of an NE through the NE node. In addition, you can

query the details of the fault alarms through the NE Panel.

Automatic Topology Discovery

The U2000 provides the automatic topology discovery function. Therefore, manual

intervention is not required and the operational expenditure (OPEX) is reduced.

The U2000 supports two methods of automatic topology discovery, as follows:

After the SNMP parameters are set on the NE based on the SNMP protocol, the NE

sends traps to the U2000 in an unsolicited manner. Then, the NE is added to the topology view on the U2000 automatically.





4-7

In automatic topology discovery, the transport NE, NE based on the SNMP protocol, and

NE based on the ICMP protocol are searched separately in batches. Then, the NE that is

searched out is added to the topology view automatically.

The Secuity NE can be added to the topology view automatically by use the function of

Batch Import NE.

The U2000 searches for the fiber/link in batches. Then, the discovered fiber/link is added

to the topology view on the U2000 automatically.

Figure 4-5 Illustration of automatic topology discovery

1. The automatic topology discovery operation is implemented step by step through a

wizard. Specifically, the wizard guides you to configure the parameters required for the

automatic discovery, such as NE type, SNMP parameters, and the IP address range.

2. After you finish configuring the parameters, the U2000 searches for the required NE

among the specified network segments according to the preset parameters. All NE (both

from Huawei and other vendors) that is based on the SNMP protocol and meets the

conditions is displayed automatically in the topology view. At the same time, the basic

configurations of the NE is uploaded automatically. In this manner, you need not

perform basic configurations on the NE again.

3. During the discovery, you can cancel the discovery at any time. In addition, you can

learn the cause if the discovery fails.

4.3 Alarm Management

In alarm management, you can monitor network exceptions in real time. It provides various

management methods such as alarm statistics, alarm identification, alarm notification, alarm

redefinition, and alarm correlation analysis. This helps the network administrator take proper

measures to recover the normal operation of the network.

Networkwide Alarm Browsing

Alarm display is classified into alarm panel display, alarm topology display, and alarm

browsing.

The U2000 supports the following alarm browsing functions:



Product Description



Issue 03 (2010-11-02)

Alarm panel display

It is used to display the number of alarms of the currently managed objects by severity

and simply provide the fault status of the system. It can be used as a monitoring panel.

Alarm topology display

When an NE reports an alarm, the NE icon in the topology view can be in different

colors according to the alarm severity. In this case, you can right-click the NE icon and

query the current alarm of the NE from the shortcut menu.

Alarm browsing

− Browsingcurrent alarms

It is used to browse the fault alarms that are currently not processed, that is,

unacknowledged and uncleared alarms.

− Browse history alarms

It is used to browse all fault alarms that were acknowledged and cleared.

− Browse alarm logs

It is used to browse all fault alarms reported by NEs.

− Browsing event logs

It is used to browse current abnormal events.

− Setting an alarm query template

You can save common query conditions in an alarm query template. Thus, next time

when you query alarms that meet the common conditions, you can use the template

directly without setting query conditions again. This helps you browse and monitor

the alarms that concerns you.

− In the handling suggestion pane of the alarm, a link is provided, which points to the

corresponding alarm reference topic in the Online Help.

In addition to the preceding functions, the U2000 provides various customized functions, as

shown in Figure 4-6 and as listed in Table 4-1.

of an NE in real time. In addition, you can query the alarm status,

refresh the status in real time, and query the details of an alarm in

the alarm activation window. You can also print the alarm

records that are received recently and meet the print conditions.

Alarm query With the alarm query function, you can query alarms by object

where an alarm occurs, function, alarm status, and alarm severity.

In addition, you can save and print the query result.

Alarm color display The severity of each alarm in the alarm list is displayed with a

corresponding color. The color can be customized.

Alarm topology

display

When an NE reports an alarm, the icon in the upper left corner of

the NE in the topology view varies with the alarm severity, or the

NE icon in the topology view can be in different colors according

to the alarm severity. In this case, you can query the current alarm

of the NE from the shortcut menu.

Alarm locating With the alarm locating function, you can select an alarm and

locate the topology object that generates the alarm (For a physical

alarm, you can locate the panel of the NE that generates the

alarm.)



Product Description



Issue 03 (2010-11-02)

Function Description

Sequence customizing Through the sequence customizing function, you can sort alarms

by field in the alarm list and customize the alarm display. In

addition, you can save alarms in the .txt, html, xls, pdf, and csv

file, and print the required alarm records.

Alarm Statistics

You can learn the alarm status through alarm statistics and alarm analysis.

U2000 can collect alarm statistics based on user-defined conditions. The alarm conditions

include the alarm name, alarm severity, alarm function type, alarm rising time, alarm status, or

a combination of any preceding items.

Alarm Masking and Alarm Correlation Analysis

NEs report a large number of alarms during maintenance, test, or new deployment. However,

you need not concern the reported alarms. Therefore, these alarms reported by the NE need to

be masked, that is, these alarms are not displayed or saved. You can set conditions to mask the

alarms or events that meet the conditions.

The U2000 provides the following means for you to perform specific correlation analysis:

alarm/event correlation analysis, intermittent alarm analysis, repeated event analysis, and

alarm/event frequency analysis, and lasting time analysis of acknowledged but uncleared

alarms.

Alarm/Event correlation analysis

This function helps to find the root alarm. The U2000 supports the analysis of the

correlation between different NEs. The system analyzes the alarms based on the

pre-defined correlation rule to mask the correlative alarms and finds the root alarm. This

helps the maintenance personnel to easily find and rectify the fault.

Intermittent alarm/repeated event analysis

This function helps you to analyze alarms that are repeatedly cleared or events that are

repeatedly reported within a short period of time. To handle these alarms or events, the

system reserves only one of these alarms or events and/or change their severities. The

reserved alarms or events record the frequency with which the intermittent alarms or





4-11

repeated events occur. In addition, the system can change the alarm or event severity

according to the pre-defined settings.

Alarm/Event frequency analysis

This function helps you to analyze the frequency with which an alarm or event occurs.

You can set a condition. Within the pre-defined period, when the number of alarms or

events exceeds the threshold, the system informs the user according to the pre-defined

correlation action.

Acknowledged&Uncleared alarm time analysis

This function helps you to analyze the time of an acknowledged but uncleared alarm.

You can set a condition. Within the pre-defined period, if the time of an acknowledged

alarm exceeds the threshold, the system changes the alarm severity.

Alarm Dumping and Acknowledging

Alarm acknowledgment helps to identify whether an alarm is processed.

Alarm acknowledgment helps you to identify a processed alarm. You can then take proper

measures by checking whether the alarm is in the acknowledged state.

Alarm dumping: It supports overflow dumping and manual dumping of alarms. Alarm

dumping is used to dump history alarms and events to files, which ensures a stable and

efficient system and saves disk space.

Alarm acknowledgment: It helps you to identify a processed alarm. You can then take

proper measures by checking whether the alarm is in the acknowledged state. The U2000

supports manual and automatic acknowledgment of alarms.

Alarm Synchronization

The U2000 supports the ability to synchronize NE alarms automatically and manually. You

can manually synchronize NE alarms by performing operations through GUI or set an

automatic synchronization policy. When the U2000 restarts or the communication with an NE

recovers, the NE sends an alarm to the U2000. This implements the automatic alarm

synchronization on the U2000.

The U2000 supports the ability to synchronize NE alarm.

Manual synchronization

You can manually synchronize NE alarms by performing operations through GUI.

Automatic synchronization

You can set an automatic synchronization policy. When the U2000 starts, when its

communication with an NE recovers, or when the LCT user logs out, the NE sends an

alarm to the U2000. This implements the automatic alarm synchronization on the U2000.

Alarms are synchronized according to the following rules:

If an alarm is cleared on the NE but uncleared on the U2000, the alarm on the U2000 is

cleared.

If an alarm exists on the NE but does not exist on the U2000, the alarm is added to the

U2000.



Product Description



Issue 03 (2010-11-02)

Alarm Redefinition

The U2000 allows you to redefine the alarms of the NE. You can redefine the alarm severity

according to the requirements.

You can use this function to change the alarm severity displayed on the U2000, thus

highlighting only the alarms that concerns you.

Alarm Suppression

U2000 supports the ability to suppress NE alarms. If you set the status of an alarm to

Suppressed, the NE does not report the alarm.

The difference between alarm suppression and alarm masking is as follows: If you enable

alarm masking, an NE still reports an alarm but the U2000 does not receive the alarm. If you

enable alarm suppression, the NE does not report an alarm.

Various Alarm Notification Means

The U2000 provides various alarm notification means. The U2000 can send notifications to

the related maintenance personnel for locating faults regardless of the time and place, which

ensures that the faults are troubleshoot in time. Figure 4-7 shows the alarm notification

means.





4-13

Figure 4-7 Various alarm notification means

The U2000 supports the following two remote notification means:

By email

You can send an alarm remote notification by email. The alarm information is sent to an

email address. The user can check the email address for alarm information received on

the alarm server.

By SMS

You can send an alarm remote notification by SMS. The U2000 sends the alarm

information to a mobile phone through the SMS device (SM modem or SM gateway)

connected to the alarm server. The mobile phone user can check the SMS for alarm

information received on the alarm server.

Alarm Jumping

The U2000 supports the alarm locating function. This function helps to jump to the topology

object that generates the required alarm. In addition, this function helps to quickly locate a

network fault, which improves the efficiency of alarm locating. Figure 4-8 shows the alarm

jumping function.

Alarm Maintenance Experience Base

You can obtain the alarm processing information from the alarm maintenance experience base.

This base stores alarm details.

The alarm maintenance experience refers to the experience summarized by customers during

the maintenance. The experience is imported to the U2000. If the same fault occurs, you can

refer to the related experience to quickly handle the alarm, which improves the efficiency of

troubleshooting.





4-15

Alarm Time Localization

U2000 can display the time when an alarm is generated, acknowledged, cleared, or received

as the local time. The U2000 can display the time based on the server time or client time.

The NE that reports an alarm and the current U2000, however, may be in different time zones.

To learn the correct alarm generation time, the U2000 automatically converts the alarm

generation time (NE time) into the local time of the client.

4.4 Performance Management

5 MSTP Network Feature Management

About This Chapter

This topic describes the functional features of MSTP NE management and network

management.

5.1 MSTP NE Management

NE management refers to the management of configurations of an NE in terms of attributes,

communication, services, protection, and clocks. The configuration data is saved to the

database of the U2000 and to the database of the NE.

5.2 MSTP Protection Subnet Management

A protection subnet is a network structure with the comprehensive self-protection function. In

the U2000, the protection subnet is a generalized concept that includes not only the network

structure with the comprehensive self-protection function, such as an MSP ring and a path

protection (PP) ring, but also the network structure without the self-protection function, such

as an unprotected ring and an unprotected chain.

5.3 End-to-End MSTP Management

End-to-end network management is also referred to as trail management. You can construct

the configuration data of end-to-end network management by searching for the data at the NE

layer of the U2000, or directly configure the data at the network layer of the U2000, and apply

the data to all the related NEs. Compared with configuring NE data on a per-NE basis,

configuring NE data by using the trail management function is faster and more convenient.

5.4 End-to-End MSTP IP Management

There is the IP feature in MSTP equipment. You can build the configuration data of

end-to-end MSTP IP network management by searching for the data at the NE layer of the

U2000, or directly configure the data at the network layer of the U2000, and apply the data to

all the relevant NEs. Configuring NE data by using the trail management function is faster

and more convenient compared with configuring NE data on a per-NE basis.

5.5 SDH ASON Management

ASON is a new generation of optical network that integrates the exchange and transport. After

a user initiates a service request, the ASON selects a route automatically, establishes and

removes connections through the signaling control, and performs network connections

automatically and dynamically. An ASON NE refers to the equipment that is equipped with



Product Description



Issue 03 (2010-11-02)

both SDH and ASON features. An ASON network is managed by the U2000 that combines

ASON and SDH features.

addition, the equipment can be configured in a one-touch manner.

In the case of 1+1 protection for the SCC board, a user can query the status of the data

backup between the active and standby SCC boards.

Optical Power Adjustment


Manage the optical power. The user can query the input power, output power and power

threshold and so on for each WDM board.

Perform the function of intelligent power adjustment (IPA) management. When a fiber is

cut off, the optical amplifier board detects the signal loss at the station. The station

reports an exceptional event to the U2000. After the user confirms the event, the optical

amplifier boards at the upstream and downstream stations reduce their output power to a

safe value to prevent the fiber maintainer from being hurt by the lasers emitted from the

cut-off fiber. After the fiber is reconnected, the optical signals restore to normal and the

optical power of each optical amplifier board automatically returns to a normal value.

Automatic level control (ALC) management: Support the adjustment modes including

wavelength count detection, power detection, and link attenuation (gain mode). The

wavelength detection mode applies to the transmission link where no service is added or

dropped or where the number of wavelengths added and that dropped are the same at the

OADM. When the spectrum analyzer unit detects that the sum of each wavelength power

greatly differs from the standard power of the corresponding wavelength count, an

exceptional event is reported to the U2000. After the user confirms the event, the user

needs to manually issue a command to adjust the attenuations of each station on the link.

The power reference mode applies to the transmission links where the number of added

wavelengths differs from the number of dropped ones at an OADM. When the optical

amplifier board detects that the output power becomes abnormal, the station

automatically issues the command to adjust the attenuation of each station on the link.

This mode does not involve the spectrum analyzer unit, and is thus cost-effective. For the

previous two modes, a user can manually control whether to enable the ALC function.

The link attenuation adjustment mode also applies to the transmission link where the

number of added wavelengths differs from the number of dropped ones at an OADM.

When the optical power is attenuated to the detection threshold, a command is

automatically issued to adjust the attenuation of each station on the link.

The link attenuation adjustment mode is also referred to as the gain mode, which compares the

difference between the line attenuation and the amplifier gain, and also compares the node gain

compensation offset. Through the adjustment of the nominal gain of the optical amplifier unit and the

attenuation value of the attenuation adjustment unit, the attenuation value is equal to the gain value, thus

ensuring the power budget of the entire link.





6-9

Perform the function of automatic power equilibrium (APE). If the MCA board at the

receive end detects that the optical power of some channels is abnormal, the station

reports an exceptional event to the U2000. After the user confirms the event, the U2000

issues a command to the optical attenuation adjustment board of the upstream station.

This board adjusts the optical power of the abnormal channel so that the optical signal

noise ratio (OSNR) of each channel at the receive end is equalized.

Perform the function of ROADM optical power equalization. After the ROADM is used

to dynamically configure the wavelength services, the WDM equipment outputs

multiplexed wavelengths. The optical power, however, may be greatly different between

each channel, especially for the newly added wavelength channels. To avoid negative

impacts on the transmission performance, the ROADM optical power equalization

function is provided. The ROADM first distinguishes between the pass-through

wavelengths and the added wavelengths. Then the DWC/WSS adjusts the optical power

of the pass-through wavelengths, and the optical attenuation adjustment board adjusts the

added wavelengths based on the wavelength flags.


Dispersion Compensation


The DCM board can conduct dispersion compensation to each band to realize dispersion

equalization.

Tunable dispersion compensators (TDCs) can be used to precisely adjust the dispersion.

The submarine system supports using a separate dispersion compensation board, such as

the TDC1 and TDC2, to perform dispersion compensation for signals at the line side of

OTU boards.

Wavelength Monitoring

The U2000 supports wavelength monitoring management for the OptiX BWS 1600G, OptiX

OSN 6800, OptiX OSN 8800 I and OptiX OSN 8800 II.

WDM PRBS

You can perform a PRBS test on a board to check the path quality. You can also check

whether the WDM link is normal before a service is available.

backup between the active and standby SCC boards.

Optical Power Adjustment


Manage the optical power, such as querying the input power, output power, and power

threshold for each WDM board.

Perform the function of IPA management. When a fiber is cut off, the optical amplifier

board detects the signal loss at the station. The station reports an exceptional event to the

U2000. After the user confirms the event, the optical amplifier boards at the upstream

and downstream stations reduce their output power to a safe value to prevent the fiber

maintainer from being hurt by the lasers emitted from the cut-off fiber. After the fiber is

reconnected, the optical signals restore to normal and the optical power of each optical

amplifier board automatically returns to a normal value.

ALC management: Support link attenuation (gain mode) as the adjustment mode. The

link attenuation adjustment mode applies to the transmission link where the number of

added wavelengths differs from the number of dropped ones at an OADM. When the

optical power is attenuated to the detection threshold, a command is automatically issued

to adjust the attenuation of each station on the link.

The link attenuation adjustment mode is also referred to as the gain mode, which compares the

difference between the line attenuation and the amplifier gain, and also compares the node gain

compensation offset. Through the adjustment of the nominal gain of the optical amplifier unit and the

attenuation value of the attenuation adjustment unit, the attenuation value is equal to the gain value, thus

ensuring the power budget of the entire link.



Product Description



Issue 03 (2010-11-02)

Perform the function of APE. If the MCA board at the receive end detects that the optical

power of some channels is abnormal, the station reports an exceptional event to the

U2000. After the user confirms the event, the U2000 issues a command to the optical

attenuation adjustment board of the upstream station. This board adjusts the optical

power of the abnormal channel so that the OSNR of each channel at the receive end is

equalized.

Perform the function of ROADM optical power equalization. After the ROADM is used

to dynamically configure the wavelength services, the WDM equipment outputs

multiplexed wavelengths. The optical power, however, may be greatly different between

each channel, especially for the newly added wavelength channels. To avoid negative

impacts on the transmission performance, the ROADM optical power equalization

function is provided. The ROADM first distinguishes between the pass-through

wavelengths and the added wavelengths. Then the DWC/WSS adjusts the optical power

of the pass-through wavelengths, and the optical attenuation adjustment board adjusts the

added wavelengths based on the wavelength flags.


Dispersion Compensation The G.652 and G.655 fibers have positive dispersion coefficient and positive dispersion

slope at 1550 nm window. After the optical signal is transmitted over a certain distance,

the accumulation of positive dispersion broadens the optical signal pulse and seriously

affects the system transmission performance. To minimize this effect, a negative DCM is

used in the network. It uses negative dispersion to compensate the positive dispersion of

transmitting fiber, so as to maintain the original shape of the signal pulse.

The OEQ NE can apply dispersion compensation to each band to reach dispersion

equalization.

This function supports 40G dispersion compensation configuration. It uses the TDC to

precisely adjust the dispersion.

Wavelength Monitoring

Wavelength monitoring uses the wavelength supervisory unit to monitor the wavelengths that

are transmitted from the WDM-side optical interface of the OTU board (including the service

convergence unit) and to control the wavelength drift. This function ensures stable

wavelengths.

in many aspects. A pair of systems periodically sends detection packets on the channel on

which session between the two systems is created. If a system does not receive any detection





7-7

packet from the opposite end in a specific time, the system regards that a failure occurs in

some part of the bidirectional channel to the adjacent system.

QoS Configuration

Quality of service (QoS) indicates the performance of the data flow that travels through a

network. The QoS is used to ensure end-to-end service quality. The QoS cannot increase the

bandwidth, but it can minimize the delay and jitter in the network by reasonably allocating

and monitoring network resources. In this way, the quality of important services is ensured.

The DiffServ (DS) domain consists of a group of network nodes that enable the DiffServ

function, that is, DS nodes. In a DS domain, all DS nodes use the same service provision

policy to realize the same per-hop behavior (PHB). The DS nodes are classified into edge DS

nodes and internal DS nodes. The edge DS nodes usually perform complex flow classification

on the traffic that enters the DS domain. Traffic of different types is marked with different

PHB service types. For internal DS nodes, you need to perform only simple flow

classification based on PHB service type.

The U2000 supports the following QoS functions:

Configure Diffsever domains.

Configure ATM CoS mapping.

Configure simple flow classification and complex flow classification.

Configure CAR and Shaping.

Configure the color blindness mode.

To simplify the operation and share some common QoS configuration parameters, the

U2000 supports creating QoS function point policy. The function point policies are as

follows: port policy, ATM policy and V-UNI ingress policy. By using these function

point policies, you can bind the CAR configuration attribute, shaping configuration

attribute, flow classification configuration attributes, WFQ schedule policy and WRED

policy attributes.

MPLS Tunnel Configuration

the following functions:

Configure IGMP Snooping protocol parameters.

Configure quick leave ports.

Manage routes.

Configure route member ports.

Query statistic information of IGMP protocol packets.

BFD Configuration

Bidirectional forwarding detection (BFD) can be used to check the Ethernet link status.

BFD is a simple Hello protocol. It is similar to the neighbor check of those famous protocols

in many aspects. A pair of systems periodically sends detection packets on the channel on

which session between the two systems is created. If a system does not receive any detection

packet from the opposite end in a specific time, the system regards that a failure occurs in

some part of the bidirectional channel to the adjacent system.

The U2000 supports the functions of performing the BFD detection on IP/GRE tunnels and

the inter gateway protocol (IGP).

The U2000 supports configuring single-hop or multi-hop BFD detection.

LPT Configuration

LPT is used to return the remote-end link status to the near end. The near-end equipment

performs operations depending on the remote-end link status. When the intermediate

transmission network of the services becomes faulty, the LPT informs the access equipment at

both ends of the transmission network to enable the backup network. That ensures the normal

transmission of the important data.

Synchronization Protocol Configuration

In the application scenario of dual-homing, the status of the peer equipment needs to be

obtained either for the MC LAG or for the cross-MC LMSP. Meanwhile, the actions on both

sides need to be negotiated based on different fault cases. With the method of adding

information of the peer end, a channel is established for control status synchronization with

the peer end. In this manner, the control packets can be transmitted and received through the

channel and link fault detection can be performed.

LMSP/MC LMSP Configuration

Linear MSP protection contains 1+1 linear MSP and 1:N linear MSP. They use the protection

channel to protect services that are transmitted on the working channel. When the working

channel fails, services are switched to the protection channel. The linear MSP applies to the

POS interface and structured STM interface.

The multi-chassis (MC) LMSP can implement the LMSP among NEs.

The U2000 supports the following functions of LMSP/MC LMSP configuration:

Create a linear MSP.

Check the linear MSP switching status.

Perform linear MSP switching.





8-9

QoS Configuration

QoS indicates the performance of the data flow that travels through a network. The QoS is

used to ensure end-to-end service quality. The QoS cannot increase the bandwidth, but it can

minimize the delay and jitter in the network by reasonably allocating and monitoring network

resources. In this way, the quality of important services is ensured.

The DiffServ (DS) domain consists of a group of network nodes that enable the DiffServ

function, that is, DS nodes. In a DS domain, all DS nodes use the same service provision

policy to realize the same per-hop behavior (PHB). The DS nodes are classified into edge DS

nodes and internal DS nodes. The edge DS nodes usually perform complex flow classification

on the traffic that enters the DS domain. Traffic of different types is marked with different

PHB service types. For internal DS nodes, you need to perform only simple flow

classification based on PHB service type.

The U2000 supports the following QoS functions:

Configure QoS profile.

Configure DiffServ domains.

Configure ATM CoS mapping.

Configure SVLAN DEI used flag.

Configure simple flow classification and complex flow classification.

Configure CAR and Shaping.

Configure the color blindness mode.

To simplify the operation and share some common QoS configuration parameters, the

U2000 supports creating QoS function point policy. The function point policies are as

follows: port policy, ATM policy, V-UNI ingress policy, V-UNI egress policy, PW policy

and QinQ policy. By using these function point policies, you can bind the CAR

configuration attribute, shaping configuration attribute, flow classification configuration

attributes, WFQ schedule policy, WRED policy and color blindness mode attributes.

Configure CoS queue mapping.

Supports the application of the QoS policy to multiple NEs.

MPLS Tunnel Configuration

The MPLS tunnel is the tunnel defined in the MPLS protocol. Independent from the service,

the MPLS tunnel realizes end-to-end transmission and carries the PWs related to the service.

See Figure 8-1. Unicast MPLS tunnel is mainly used to transparently transmit point-to-point

PWE3 services.

Template Management provides some default configuration templates. When you reference a

template, the attribute settings on the template automatically apply to the configured resource.


Management


Product Description



Issue 03 (2010-11-02)

A template has the following features:

Offline configuration

Global templates are created in advance and saved on the U2000 instead of being created

on a device. Thus, you can create global templates when devices are offline or do not

exist. The creation of global templates is irrelevant to the device status.

Global validity

After a global template is created, this template can take effect on all the devices

managed by the U2000. It can be referenced by a type of device or none of the devices.

Little duplicate data

− After a global template is applied to a type of device, if the template data on some

devices is the same, the U2000 keeps only one template data record for these devices.

− When a device references a global template, the U2000 does not adds a record of

template data. Instead, the U2000 records the reference relation between the device

and global template.

A global template can be referenced by a large number of devices of the same type,

which helps to reduce recorded template data and facilitate maintenance.

Main Templates

The main templtes are as follows:

ACL template

ACLs can be used to control the access of user packets that flow into ports. Configuring

ACLs in batches simplifies the configuration of the defense against attacks on the

network access side. When you configure the firewall on the network access side, you

need to configure ACL matching rules, such as the restriction on a MAC address and the

restriction on an IP address. If a rule needs to be applied to multiple interfaces on

different routers, configuring the rule at every point is time-consuming and increases the

costs of management and maintenance.

QoS template

The main applications of network QoS are as follows:

− CBQoS template, and it can be applied to interfaces on NEs in batches.

− DS domain template, and it can be applied to interfaces on NEs in batches.

− HQoS template, and it can be applied to interfaces on NEs in batches.

− PQ template, and it can be applied to interfaces on NEs in batches.

− Interface CAR template, and it can be applied to interfaces on NEs in batches.

VPN service template

The service template is used to perform batch configurations for multiple devices when a

VPN service is created or configured. In this manner, the efficiency of service

deployment is greatly improved.

Switch EPON template

When you configure multiple ONU services, you can manage ONUs uniformly by

configuring templates to improve configuration efficiency.

The U2000 provides intelligent result analysis. You can manually customize the

thresholds of test case indicators such as delay, jitter, and packet loss ratio in the result

analysis template and the result analysis policy according to the related service level. In

this manner, you can quickly determine the network status.

Test Diagnosis Management

Through test diagnosis management, you can test the connectivity and QoS of a network and

diagnose network faults according to the test results. Test diagnosis management helps to

narrow the range of fault diagnosis and reduce the time of fault location and rectification.

A test diagnosis tool consists of the following parts:

Test suite

− A test suite is made up of multiple test cases. Created according to user test requests,

a test case is the entity of a test tool based on the application layer, transport layer,

network layer, data link layer, and MPLS services. The test suite is a group of test

tools organized according to certain test scenarios.

− You can take a test suite as a performance unit and perform all the test cases or

optionally perform some test cases in the test suite. Then you can diagnose network

QoS according to the parameters shown in the test results, such as delay, jitter, and

packet loss ratio.

Diagnosis policy


Management


Product Description



Issue 03 (2010-11-02)

The U2000 provides multiple running policies for test suites. You can run the test suite

associated with a certain running policy at a specified time daily, weekly, or monthly.

Network scanning

It collects network information through network synchronization and tests the

connectivity of partial types links on the network. The U2000 provides real-time

scanning and allows you to stop running scanning tasks. The U2000 also provides the

traceroute function for you to locate faults.

History data

The history data is the records of test suite operations. You can filter and query history

data according to conditions such as the test suite name, test result, or test time, and

export query results.

Diagnosis result analysis

It provides intelligent result analysis. You can manually customize the thresholds of test

case indicators such as delay, jitter, and packet loss ratio in the result analysis template

and the result analysis policy according to the related service level. In this manner, you

can quickly determine the network status.

10.3 Centralized Security Policy Configuration

Deploying a set of security devices with comprehensive technologies during network security

construction does not mean that the network is under stable and reliable security protection.

In network security maintenance, even deploying a satisfied security policy scheme for a

small-sized local network is a rather complex task. Designing and deploying a set of reliable

security protection policies for a large-scale network, accordingly, is a fairly hard and

challenging task.

An industry-leading security policy design, configuration, and management system is worked

out upon the aim of making a security configuration and management center. With this system,

the truly reliable and stable network security protection can be implemented on the basis of

the security devices deployed on the network.

It has the following features:

Policy package management

A policy package can be used to manage all the security devices on the whole network

and sort the protection tasks on each security device into security policy, attack defense,

and service port mapping.

Users can create their own policy packages and include the configuration tasks in the

policy packages. Users can also perform operations such as creating, deploying,

undeploying, and verifying policy packages. A policy package can cover all the network

security configuration and management tasks of a user on a network.

Configuration and management ranges

Security policy

Attack defense

Service port mapping

Policy resource

Policy recovery

During network security management and maintenance, how to ensure the data

consistency between the NMS and devices so that the actual network configurations can

be accurately displayed on the NMS?

Policy recovery can restore the security policies and attack defense configurations

deployed on devices and the used resources of devices to the NMS, thereby achieving

the data consistency between the NMS and devices.

Policy audit

Auditing the configuration data difference between the NMS and devices helps to ensure

the data consistency and make users to fully trust the NMS when using it.

Security policy configuration and management modes of two dimensions

1. Service-dimension configuration: manages the configurations when the services are

deployed on multiple or all devices on the network. This helps users to manage and audit

services from the point of networkwide view. On a large-scale network, users do not

need to check and configure services on devices one by one. Therefore, missing

configurations are reduced, and security services can be configured reliably and efficiently.



Product Description



Issue 03 (2010-11-02)

2. Single NE-dimension configuration: manages the configurations of a single NE. Users

can select an NE to check security configurations, create, modify, deploy, and undeploy

configurations, and import the configurations of other NEs to this NE.

Policy deployment status display

Whether a policy is deployed, whether the deployment is successful, and whether the

deployment status is the same as that on the device are displayed. This helps to prevent

the repeated deployment of a policy that is already deployed.

History record query

The detailed policy package configuration and maintenance procedures are recorded. The

history operations that users perform on policy packages can be audited.

policy packages, view the deployment and audit result of policy packages.

By changing operations based on single policies and single devices to centralized operations

based on batch policies and multiple devices, this feature increases operation efficiency and

reduces maintenance cost.

The policy packages verifying function ensures the correctness of policy package

configurations and correlations among the policies within the same policy package. With the

policy verifying function, you can correctly deploy policy packages on devices and avoid

repeated modifications due to configuration errors during policy deployment.

Policy auditing is to audit the policy configuration differences between the NMS and device,

so as to determine whether the policy needs to be deployed or discovered.

Policy discovery is to recover the data synchronized to the database to the NMS for

management.

The rights to perform various operations on policy packages are under control. Operations on

policy packages are recorded in logs for the policy maintenance personnel to monitor and

manage policies.

10.3.4 Policy Resource Configuration

The configuration of policy resources includes the configuration of service,addess sets,period

and ports sets.

Configuring services, address set, time range, and port set

− Services

As flexible support for the IP protocol, security services can be classified into TCP

services, UDP services, ICMP services, and other services. The U2000 provides some

basic services by default. You can create different services by adding different

parameter settings to the same protocol. Different types of services can form a service

group. A rule corresponds to one or multiple services. In the case where a rule

corresponds to multiple services, these services can be in a service group or map to

these services. When you log in to the U2000 for the first time, the U2000 provides

some services by default.

− Address set

When setting source and destination addresses on the U2000, you can either set

single IP addresses or set address sets.

− Time range

Time ranges are classified into two types: continuous time ranges and periodic time

ranges. A continuous time range starts from one time point and ends at another time

point. Rules are valid only within the time range. A period time range is on a weekly

cycle. You need to set the start time and end time of a day and specify on which days

of a week the rules are valid. Then the rules will take effect on a weekly cycle.

− Port set

A port set is a collection of single, continuous, or discontinuous port numbers,

specifying the ports through which the server can provide services. The value of a

port set ranges from 0 to 65535.

Configuration log server

Binary flow logs of devices can be sent to binary servers via configuration of log server.

10.3.5 Mapping Service

14 ONT Management

The U2000 supports the management of EPON terminals in the OAM mode and GPON

terminals in the OMCI mode. In this manner, the terminals are managed in a centralized

manner, which saves the maintenance workload.

To manage xPON terminals, the U2000 adopts two solutions, namely, SNMP+OMCI and

FTP+OMCI.

The objects managed by the ONT L2 protocol and protocols at lower layers provision

multicast IPTV and data services by using the SNMP+OMCI solution.

The VoIP services are provisioned through the FTP+OMCI solution. The N2000 BMS

generates a .xml configuration file and then uploads the file to the FTP server. The OLT

obtains the configuration file from the FTP server, loads it, and then sends it to the ONT

through the OMCI. Finally, the service configuration of the ONT is complete.

The U2000 supports the automatic batch upgrade of ONTs.

Supports the batch upgrade of ONTs.

Supports the scheduled task upgrade management.

Supports the upgrade of offline ONTs, that is, automatic upgrade when the ONT is

connected.

15.2 HA System

The high availability (HA) system helps you improve the running reliability of the U2000

server.

The non-distributed U2000 server uses a 1+1 scheme. If the active site fails, the U2000 can be

switched to the standby site so that the U2000 application is not interrupted.

The U2000 supports distributed cluster. For better stability and risk resistance capability, the

distributed cluster uses a 1+1 scheme. If a slave server fails, the master server fails, the

database is faulty, IP addresses conflict, or the key process fails to be switched, you can

switch the distributed cluster to the standby distributed cluster without interrupting the U2000.

The protection mechanism of an HA system has two aspects:

Database synchronization and backup between the active and standby sites

Switching the application program between the active and standby sites

The U2000 provides the following HA schemes:

HA system (Veritas 1+1 hot standby): Applicable to remote hot standby of the

non-distributed system, featuring automatic switching.

HA system (Veritas distributed hot standby): Applicable to remote hot standby of the

distributed system on SUSE Linux OS, featuring automatic switching.

15.3 DCN Protection

You can use a data communication network (DCN) to connect the U2000 to a standby

gateway NE (GNE). This improves the reliability of the communication connection between

the U2000 and equipment.

The communication between non-GNEs and the U2000 is forwarded by the GNE. In the

U2000, you can set the active GNE and standby GNE for NEs in advance. When the

communication between the active GNE and the U2000 is interrupted, the U2000

automatically switches to the standby GNE for communication, so that the communication

between the U2000 and NEs is not interrupted. When the communication between the U2000

and the active GNE recovers, the U2000 determines whether to use the active GNE again

according to the preset revertive mode.

15.4 Disk Mirroring

The disk mirroring function helps you improve the reliability of disk data on the U2000

server.

If the server is a Sun workstation with more than two hard disks, disk mirroring can be

installed together with the U2000. After you create disk mirroring, if the active disk fails, you

can use a command to switch the data to the standby disk, to restore the working data and

parameter settings before the active disk is damaged.

15.5 Data Backup

The data backup function helps you improve the reliability of important U2000 data.

The security of network data is a concern for users. The U2000 provides the following

solutions listed in Table 15-2.

17 Management Capability

About This Chapter

Introduce the manageable equipment and the management capability of the U2000.

17.1 Management Capability

The management capability of the U2000, on the basis of satisfying the preceding

performance indexes, can be measured by the maximum number of NEs it manages.

17.1 Management Capability

The management capability of the U2000, on the basis of satisfying the preceding

performance indexes, can be measured by the maximum number of NEs it manages.

Currently, a set of U2000 can manage a maximum of 15,000 physical NEs, 20,000 equivalent

NEs and 100 clients. This conclusion is drawn after the tests under a certain environment and

objectively reflects the actual management capability of the U2000.

Management capability: In this document, management capability refers to the capability

of the NMS to manage network resources, which are expressed in the number of

equivalent NEs.

Equivalent NE: The functional features, cross-connect capacity, and number of

boards/ports/channels are specific to NEs of different types. As these NEs require

different resources of the NMS, the number of NEs that can be managed by the NMS

depends on the NE types. For easy description and calculation of the management

capability, the concept of equivalent NE is defined so that NEs of different types or a

number of ports can be converted to equivalent NEs by an uniform criteria according to

the system resources required by them. The system resources required by an equivalent

NE is equal to the resources for managing an STM-1 transport NE.

Equivalent coefficient: The equivalent coefficient refers to the ratio of the resources used

by physical NEs or ports to the resources used by equivalent NEs. Equivalent coefficient

= (Resources used by physical NEs or ports)/(Resources used by equivalent NEs)

The management capability of the U2000 in a network that consists of different types of NEs

is affected by the following factors:

The key technical specifications include the number of equivalent NEs, number of

clients, and number of physical NEs.



Product Description



Issue 03 (2010-11-02)

The management capability of the U2000 also depends on the hardware and varies with

the hardware configuration.

The system limits the number of physical nodes. Hence, the number of physical nodes is

a restriction for the management capability.

The management capability refers to the maximum number of equivalent NEs that can

be managed by the U2000 on certain hardware configuration conditions.

If a client also runs on the computer where the server is running, the management

capability is reduced by 50%. Hence, it is recommended that you run the client and

server on different computers.

Virtual NEs are not included in the management capability. A pre-configured NE is equal

to a real NE. One third-party NE is equal to one equivalent NE, and can only be

discovered instead of being managed. The equivalent coefficient of the OEM equipment

is calculated in the way similar to Huawei equipment.

Generally, the number of equivalent NEs that the U2000 can manage is calculated according

to the following rules:

Number of equivalent NEs = <Number of equivalent NEs in the transport domain> +

<Number of equivalent NEs in the IP domain> + <Number of equivalent NEs in the

access domain>

<Number of equivalent NEs in the transport domain> = (Number of transport NEs of

type_I x Equivalent coefficient + ... + (Number of transport NEs of type_n x Equivalent

coefficient)

For example, there are 5 OptiX OSN 9500 (equivalent coefficient: 10), 10 OptiX OSN 7500 (equivalent

coefficient: 6.5), and 100 OptiX OSN 3500 (equivalent coefficient: 4.5). Then, you can calculate the

number of equivalent NEs in the transport domain as follows:

Number of equivalent NEs in the transport domain = 5 x 10 + 10 x 6.5 + 100 x 4.5 = 565

<Number of equivalent NEs in the IP domain> = (Number of IP NEs of type_I x

Equivalent coefficient) + ... + (Number of IP NEs of type_n x Equivalent coefficient)

For example, there are 5 NE5000E (equivalent coefficient: 10), 200 S5300 (equivalent coefficient: 1.25),

and 1000 CX200 (equivalent coefficient: 0.625). Then, you can calculate the number of equivalent NEs

in the IP domain as follows:

Number of equivalent NEs in the IP domain = 5 x 10 + 200 x 1.25 + 1000 x 0.625 = 925

<Number of equivalent NEs in the access domain> = Number of FTTx OLT equivalent

NEs + Number of FTTx MDU equivalent NEs + Number of MSAN equivalent NEs +

Number of DSLAM equivalent NEs + Number of equivalent NEs of other access

equipment

Number of FTTx OLT equivalent NEs = (Number of ONTs x Equivalent coefficient) + (Number of

MDUs x Equivalent coefficient) + (Number of P2P ports x Equivalent coefficient)

Number of FTTx MDU equivalent NEs = (Number of ports of type_I x Equivalent coefficient) + ...

+ (Number of ports of type n x Equivalent coefficient)

Number of MSAN equivalent NEs = (Number of ports of type_I x Equivalent coefficient) + ... +

(Number of ports of type n x Equivalent coefficient)

Number of DSLAM equivalent NEs = (Number of ports of type_I x Equivalent coefficient) + ... +

(Number of ports of type_n x Equivalent coefficient)

Number of equivalent NEs of other access equipment = (Number of NEs of type_I x Equivalent

coefficient) + ... + (Number of NEs of type_n x Equivalent coefficient)

The basic unit of an equivalent NE of the U2000 is OptiX Metro 1000.





17-3

The comparison coefficient of an equivalent NE of the U2000 to the equivalent NE in

each domain is as follows:

− 1 equivalent NE in the transport domain = 1 equivalent NE of the U2000

− 4 equivalent nodes in the IP domain = 1 equivalent NE of the U2000

− 3.3 equivalent nodes in the access domain = 1 equivalent NE of the U2000

The management scales of the U2000 are defined as follows:

− Small-scale network: less than 2,000 equivalent NEs of the U2000

− Medium-scale network: less than 6,000 equivalent NEs of the U2000

− Large-scale network: less than 15,000 equivalent NEs of the U2000

− Extra-large-scale network: less than 20000 equivalent NEs of the U2000

Conversion between monitored instances to equivalent nodes:

Monitored instances are converted into physical equivalent nodes as follows: 2

monitored instances = 1 equivalent NE of the U2000

Conversion between service resources to equivalent NEs.

Service resource management needs to be converted into a certain number of equivalent

nodes. The formulas for calculating the equivalent nodes are as follows:

− For 1-20,000 service resource licenses, Equivalent nodes of services = Total

equivalent nodes x 20%

− For 20,001-60,000 service resource licenses, Equivalent nodes of services = Total


− For 60,001-100,000 service resource licenses, Equivalent nodes of services = Total


The management capability of the U2000 varies with hardware platforms, as shown in Table

17-1.

Product Description A Glossary

A Glossary

A

Abnormal Resource When the NMS carries out the operation of device resource polling

on the device management module or the module is refreshed

manually, the physical resources of some devices, such as the card,

sub-card and port, cannot be accessed because they have been

deleted or have some faults. So, after the NMS carries out the

operation of device resource polling on the device management

module or the module is refreshed manually again, the result of

polling the physical resources differ from the first time. The

physical resources that cannot be polled in the second time are

called the abnormal resource.

AIS insertion If there are excessive errors in a channel, AIS can be inserted in this

channel to indicate it is unavailable. For a line board, you can set

whether to insert AIS when there are excessive errors in the B1, B2

and B3 bytes. For a tributary board at the E1 or T1 level, you can

set whether to insert AIS when there are excessive errors in BIP-2.

For a tributary board at the E3 level or higher, you can set whether

to insert AIS when there are excessive errors in the B3 byte.

AIS Alarm Indication Signal. A signal sent downstream in a digital

network if an upstream failure has been detected and persists for a

certain time.

Alarm correlation

analysis

In the case alarm2 is raised within five seconds after alarm1 is

raised, and alarm2 complies with the conditions defined in the

alarm correlation analysis rule, you can either suppress the alarm2

or raise its severity level according to the behavior defined in the

alarm correlation rule. Such a process is called alarm correlation

analysis.

Alarm Level Alarm level is to identify the severity of an alarm or event. It is

divided up into four levels: critical, major, minor, warning alarm.

Alarm Status Device reports the trap information to NMS. NMS displays the

received information on the alarm start on the topological view.

The alarm state contains four types: urgent alarm, important alarm,

subordinate alarm and prompt alarm.

Auto Discovery NMS tests the remote device by using PING or the SNMP

parameter module configured in advanced to discover the IP device

or the device that supports SNMP and to add the discovered devices

automatically.

Alarm reversion For the port that has already been configured but not actually loaded

with services, this function can be used to avoid generating relevant

alarm information, thus preventing alarm interference.

Alarm severity According to ITU-T recommendations, the alarm is classified into

four severities: Critical, Major, Minor, and Warning.

Alarm suppression The suppressed alarm of a specific object is not reported. The object

here may be the networkwide equipment, a specific NE, a specific

board and even a specific function module of a specific board.

Alarm A visible or an audible indication to notify the person concerned

that a failure or an emergency has occurred. See also Event.

ATM protection

group

An ATM protection group refers to the logically bound ATM VP

network or subnetwork connections that share the same physical

transmission channel. In the VP group (VPG), a pair of VP

connections (working connection and its protection connection) is

used for monitoring the automatic protection switching, called

monitoring connections (APS VPCs). If the monitoring connections

switch over, the whole VPG will switch over to quicken the ATM

protection switching (as quick as the protection switching of the

SDH layer.

ALS Automatic Laser Shutdown. ALS is turned on when the optical

interface board does not carry services or the optical fibre is faulty.

Its service life can be prolonged by decreasing the duration during

which laser is on.

Attribute Property of an object.

test baseline, to provide a basis of comparison and analysis for the

following line test result.

Baseline collection

test

One of the test types for submarine line. In the case of deployment

or fault restoration, or when updating the baseline is required, you

need to collect the baseline, to provide reference for comparison

tests, and alerts or alarms.

Binding In virtual concatenated payload configuration, designating one

binding number to identify the VC4s of the same virtual

concatenated payload is called "bind". If a fault occurs to one of the

bound services, all bound services will switch as a whole.

Optical time domain

reflectormeter

OTDR is an optical fault locator and analysis tool for optical fiber

networks. The OTDR features a light, compact, hand-held design

with an intelligent user interface that is easy and quick to use. The

color LCD display and backlight design makes testing work more

comfortable and convenient, whether during daylight or at night.

Out-of-Service

Mode

One of the test modes for submarine line. By transmitting detection

light with high power, the out-of-service test can detect the fiber

status and repeater status, to realize the status detection and fault

point location after fiber cut. In general, when detecting that a line

is abnormal during a test in in-service mode, you can carry out a test

in out-of-service mode to locate the fault.

OWSP Optical Wavelength Shared Protection. OWSP is a bidirectional

ring, where each node is equipped with an OWSP. There are two

channels (λ1 and λ2) in the main optical path on the internal and

external rings in each span on a ring. The fibre and the OWSP on

the main optical path are connected with the optical ports inputting

λ1 and λ2 on the mux/demux board (unnecessary to be connected

with the OTU), and thus λ1 and λ2 can be added and dropped at

every node.

P

Path protection The working principle of path protection: When the system works

in path protection mode, the PDH path uses the dual-fed and signal

selection mode. Through the tributary unit and cross-connect unit,

the tributary signal is sent simultaneously to the east and west lines.

Meanwhile, the cross-connect matrix sends the signal dually sent

from the opposite end to the tributary board through the active and

standby buses, and the hardware of the tributary board will

selectively receive the signal from the two groups of buses

automatically according to the AIS number of the lower order path.

Path A trail in a path layer.

Performance register Performance register is the memory space for performance event

counts, including 15-min current performance register, 24-hour

current performance register, 15-min history performance register,

24-hour history performance register, UAT register and CSES

register.

Performance

threshold

Performance events usually have upper and lower thresholds. When

the performance event count value exceeds the upper threshold, a

performance threshold-crossing event is generated; when the

performance event count value is below the upper threshold for a

period of time, the performance threshold-crossing event is ended.

In this way, performance jitter caused by some sudden events can

be shielded.

Protection strategy In case the service route provides multiple service protections,

different protection strategies can be selected as required. Protection

strategy refers to the protection mode given the priority in use for

the trail: protection, no protection, and extra traffic. Of the above,

the protection preference is divided into trail protection and

sub-network connection protection.

Protection subnet The resources that form a protection subnetwork include NEs and

fiber cables. The creation of the protection subnetwork actually

means that corresponding logical system is configured for each NE

by means of creating the protection subnetwork, the optical

interfaces (or VC4) of each board are mapped into the logical

system, and then these independent logical systems are connected

with one another to form a complete network structure.

Packets Loss Ratio This index shows the packet loss ratio after many Ping operations

ROADM Reconfiguration Optical Add/Drop Multiplexing. ROADM helps

you to terminate or pass through any one wavelength at every node

without affecting the existing services. At the same time, ROADM

can change wavelengths through the NMS remotely, to adjust

wavelengths added or dropped in a quick and convenient manner. In

addition, ROADM enables power equalization at path level through

a built-in power equalization function, and thus adjusts power for

pass-through paths in a better way than a band-based dynamic gain

equalizer (DGE) does.

Route The IP route selection is in table driving mode. In each host and

each router of the Internet, there is a routing table that contains

information about how the service is transmitted from the source to

the sink, providing a basis for route selection. Ethernet static

routing in ET1 refers to the mapping relationship between the

Ethernet port and the bound path. Its routing type includes port

routing and VLAN routing. Port routing: It means configuring a

route between the Ethernet port and the bound path port, which is

usually used for point-to-point networking communication; VLAN

routing: It means configuring a route between the Ethernet port and

the bound path port based on the VLAN service. It can be used

flexibly in point-to-point, point-to-multipoint or

multipoint-to-multipoint communication. The implementation is to

divide and converge the data stream according to the VLAN flag of

the packet. As a VLAN flag can be added to the Ethernet port, the

equipment can be applied more flexibly.

Report The report that is generated manually in a real-time fashion.

RTT RTT is the round trip time, which is the time delay of the ping task.

the periodical running of the schedule tasks.

Script A list of instructions for performing a specific task or action,

written in a scripting language.

SDH NNI SDH Network Node Interface. It is applied to build

communications connection with the equipment beyond the NMS

management area. Usually, the NM creates an SDH NNI by

creating a logical system on the port of an idle line board, and the

NE must be a TM without protection and fibre connection.

Subnet mask Also referred to as the network mask off code, it is used to define

network segments, so that only the computers in the same network

segment can communicate with one another, thus suppressing

broadcast storm between different network segments.

Subnet number Subnetwork number is used to differentiate the different network

sections in the sub-network conference. Actually it is the first

several digits (one or two) of the user phone number. An orderwire

phone number is composed of the sub-network number and the user number.

TMN Telecommunications Management Network. The entity which

provides the means used to transport and process information

related to management functions for the telecommunications

network.

Topology The NMS topology is a basic component of the man-machine

interactive interface. The topology clearly shows the structure of the

network, the alarms of different NEs, sub-networks in the network,

the communication status as well as the basic network operation

status.

Trail management

function

A network level management function of the NMS. Through trail

management, you can configure end-to-end services, view graphic

interface and visual routes of a trail, query detailed information of a

trail, filter, search and locate a trail quickly, manage and maintain

trails in a centralised manner, manage alarms and performance data

by trail, and print a trail report.

Trail A trail is a kind of transport entity, mainly engaged in transferring

signal from the input of the trail source to the output of the trail

sink, and monitoring the integrality of the transferred signal.

According to the different levels of the trail, the trail includes

various types (OTS, OCH, OMS, SPI, RS, MS, VC4 server trail,

VC4, VC3 and VC12). Among them, OTS, OCH and OMS

represent the trails in a DWDM layer network. For the ADM and

TM equipment in the SDH network, each optical fibre connection

corresponds to an SPI, RS or MS trail, and a trail is the general

name for service carriers, including SDH and PDH services.

Tributary loopback A fault can be located for each service path by performing loopback

to each path of the tributary board. There are three kinds of

loopback modes: No loopback, Outloop and Inloop.

Threshold The alarm range will be defined after the performance data is

collected. The threshold contains the upper and lower one, related

with the unit and index.

object generates 10 consecutive severely errored seconds (SES) and

the SESs begin to be included in the unavailable time. The event

will end when the bit error ratio per second is better than 10-3

within 10 consecutive seconds.

UNI UNI is the abbreviation for User Network Interface. It identifies the

interface between the user and the ATM network node.

Unprotected Services transmitted through an ordinary way, once a failure or

interruption occurs, the data cannot be restored for lack of

protection mechanism.

authorities. The default user group includes: system administrator,

system maintainer, system operator and system supervisor. The

attributes of user set include name and detailed description.

User The user of the NMS client, and the user and his/her password

define the corresponding authority of operation and management of

the NMS.

V

VC4 loopback The fault of each VC4 path on the optical fibre can be located by

setting loopback for each VC4 path of the line. There are three

kinds of loopback modes: No loopback, Outloop, Inloop.

VC4 server trail The path rate of the VC4 server trail is 150.336Mbit/s. The VC4

server trail provides transparent channels (that is, circuit group) for

circuit-layer network nodes (for example, a switch) in a path-layer

network, and acts as the basic unit of inter-office communication

path. When the VC4 server trail is configured, only the higher order

cross-connection of VC4 is generated in the intermediate NE, but

no cross-connection is generated at the two ends, that is, no service

is added/dropped. Therefore, the VC4 server trail is not a traditional

service. It is only the basis for VC3 and VC12 trail creation.

VCI The VCI, shorted for Virtual Channel Identifier, occupies 16 bits in

both NNI cell or UNI cell. It indicates the virtual channel in the

path. The VPI and VCI together indicate a virtual connection.

can be planned according to the domain, maintenance relationship

and so on.

Edits and displays the rule of the topology data or the filter

conditions. It can be tailored according to the requirements

Virtual fibre A virtual fibre is created between SDH equipment that has WDM

equipment in between. From SDH equipment perspective, creation

of virtual fibres disassociates its fibre connection with WDM

equipment and prevents impact on the auto fibre search function,

ensuring independence of SDH trail management.From WDM

equipment perspective, its service bearer layer is a virtual fibre

instead of a true one after the virtual fibre is created. Deletion of the

true fibre does not affect trail management.

Virtual NE Like a common NE, a virtual NE is also displayed with an icon on a

view, but it is only an NE simulated according to the practical

situation, which does not represents an actual NE. Therefore, the

actual status of this NE cannot be queried and its alarm status

cannot be displayed with colours. Usually, when the trail

management function is used for the NEs or sub-networks the NMS

cannot manage, or the equipment is interconnected with other

vendors' NEs for service configuration, the end-to-end service

configuration method and the trail management capability are

provided.

VLAN ID Namely, it is the virtual LAN identifier. One Ethernet port can

support 4K VLAN routes, and one NE can support up to 8K VLAN

routes.

VPI The VPI, shorted for Virtual Path Identifier, occupies 12 bits in the

NNI cell, and 8 bits in the UNI cell.

W
