1Managing WDM Protection SubnetsAbout This Chapter

A protection subnet has a structure of providing complete self-protection functions. The purpose

of managingprotection subnets is to configure and display network protection, for example,

browsing, deleting, modifying and searching for protection subnets, managing isolated nodes.

1.1 Basic Concepts

According tothe layered structure of transport network, protection subnet, belonging to the

network layer, refers to a network structure that has a comprehensive self-protection function.

The protection subnet is a network unit of composing the optical transport network. To have a

good understanding of the protection subnet, you need to learn some basic concepts of the

network layer.

1.2 Searching for Protection Subnets

By searchingfor a protection subnet, the configured protection attributes at the NE layer on the

U2000 are synchronized to the network layer on the U2000 to create protection subnets

automatically.

1.3 Configuring 1:N Wavelength Protection

On the U2000, you can create 1:N wavelength protection groups, search for 1:N wavelength

protection subnets, and perform an external switch from 1:N wavelength protection subnets.

1.4 Configuring Protection for an ODUk SPRing

By using the U2000, you can query the protection subnet resources for an ODUk SPRing, create

an ODUk protection group, search for the ODUk SPRing, perform data consistency check onthe ODUk SPRing, set the protection subnet parameters for the ODUk SPRing, and delete an

ODUk SPRing.

1.1 Basic Concepts

According to the layered structure of transport network, protection subnet, belonging to thenetwork layer, refers to a network structure that has a comprehensive self-protection function.

The protection subnet is a network unit of composing the optical transport network. To have a

good understanding of the protection subnet, you need to learn some basic concepts of the

network layer.

1.1.1 Protection Subnet

A protection subnet refers to a network architecture that has a comprehensive self-protection

function. It is a network that composes the optical transmission network.

1.1.2 Isolated Node

An isolated node is not equal to an isolated NE. An isolated node refers to a special logical

system that is independent from any protection subnet. An isolated node does not belong to anyprotection subnet.

1.1.1 Protection Subnet

A protection subnet refers to a network architecture that has a comprehensive self-protection

function. It is a network that composes the optical transmission network.

In the U2000, a protection subnet is a network level concept. NEs and fiber connections are the

basic elements required to construct a protection subnet. You should create NEs, perform basic

configurations for them, and then properly create fiber connections between the NEs. You should

have access to sufficient resources to create a protection subnet.

1.1.2 Isolated Node

An isolated node is not equal to an isolated NE. An isolated node refers to a special logical

system that is independent from any protection subnet. An isolated node does not belong to any

protection subnet.

An isolated node is a node that is configured at NEs but cannot or does not compose a protection

subnet with other nodes. Currently, the WDM equipment supports the 1:N optical path protection

subnet and the ODUk SPRing protection subnet. The network node that is configured with the

1:N optical path protection group or the ODUk SPRing protection group but does not belong to

any protection subnet is an isolated node.

An isolated node should not exist in a transmission network that runs normally. The reason for

the existence of any isolated nodes can be as follows:

l The configuration is incorrect at the NE side.

l The fiber that should be connected to the node is not created on the U2000.

1.2 Searching for Protection Subnets

By searching for a protection subnet, the configured protection attributes at the NE layer on the

U2000 are synchronized to the network layer on the U2000 to create protection subnets

automatically.

group. To create 1:N (N8) optical channel protection, you need to create a 1:N (N8) optical

channel protection group for each node.

2.1 Managing WDM Trails

This section describes how to manage end-to-end WDM services based on the trail management

function of the U2000.

Prerequisite

A U2000 user can manage all the trails that the user creates. To manage a trail that is created by

another U2000 user, a U2000 user must meet any of the following conditions:

l The U2000 user belongs to the Administrators user group.

l The right to manage the required trail is allocated to the U2000 user.

2.1.1 Configuration Task Flow

A configuration task flow describes the operation tasks that manage an WDM network by using

the end-to-end function of the U2000. In addition, the relationships between the operation tasksare described.

2.1.2 Basic Concepts

This section describes the basic concepts of the WDM end-to-end management.

2.1.3 Creating WDM Trails by Trail Search

After a new network is set up or services are configuredon a per-NE basis, you need to perform

an WDM trail search so that you can manage configured services by using the trail management

function.

2.1.4 Configuring WDM Trails

After searching out the relevant trail information on the U2000, you can create OCh, ODUk or

client trails by specifying the sources and sinks of the trails.2.1.5 Creating a Platinum Service

In a platinum service group, the WDM trails do not pass through the same NE, fiber or fiber/

cable pipe, sothat the risk that multiple trails are interrupted is lowered.

2.1.6 Bindinga Platinum Service Group

You can bind a trail or trails when you need to add an existing trail to a platinum service group

or bind existing trails as a platinum service group.

2.1.7 ServiceAuthorization Management

If there are multiple service trails maintained by differentoperators, they may care about only

the trails in their own responsibility but ignore the other services. Service authorization can filter

the information not in concern of an operator, who then views and manages only the trails in theresponsibility. In this manner, the management and maintenance efficiency is improved.

2.1.8 Viewing WDM Trails

This section describes how to view the connection relation of all boards on a WDM NE.

2.1.9 Maintaining WDM Trails

The end-to-end trails are carriers of services of the customers. In the routine maintenance, the

administrator and maintainer must find out the status of the trails to ensure that all the services

are transmitted correctly.

2.1.10 Modifying WDM Trails

Due to service requirements, sometimes, you need to modify the configuration of a WDM trail.

U2000 supports manually modifying the source and sink of an exisiting WDM trail and the trailnames in batches, instead of creating WDM trails. This greatly simplifies the operations.
