1Managing RTN Protection SubnetsAbout This Chapter

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

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

viewing, creating, deleting, modifying and searching for protection subnets, managing NNIs,

and managing isolated nodes.

1.1 Basic Concepts

According to the 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 thenetwork layer.

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.

1.3 Configuring an MSP Ring

In a ring network topology or when a service exists between rings or between a ring and a chain,

you can configure an MSP ring to protect the service if a fault occurs.

1.4 Configuring Linear MSP

In the linear network topology, you can configure the linear MSP to protect the network sectionby section.

1.5 Creating an Path Protection Ring

A path protection ring is used to protect a private ring network. Normally, the protection path

also transmits the primary service. STM-N signals can be quickly protected at a VC level without

runnig a switching protocol.

1.6 Configuring a Non-Protection Ring

When services on a ring do not need protection, you can configure a non-protection (NP) ring.

All timeslots on the ring can be used to transmit services.

1.7 Configuring a Non-Protection Chain

If a service in the chain does not need to be protected, you can configure a non-protection chain.In this case, all the timeslots in the chain can be used to transmit the service.

1.8 Configuring DNI Protection

You can create DNI protection for the interworking nodes of two rings, and for the protection

of the interworking services between two ring networks. The network can be a combination of

equipment from different vendors or different protection modes. Moreover, DNI is also available

to fiber and node failures.

1.9 Configuring IF 1+1 Protection

IF 1+1 protection uses a standby path to protect an active service.

1.10 Configuring IF N+1 Protection

IF N+1 protection uses a standby path to protect N active services.

1.11 Maintaining Protection Subnets

When the protection status of a network is abnormal or when adjusting a network, you need to

maintain the protection subnet.

1.12 Deleting Protection Subnets

When an existing protection subnet is not suitable, you can delete the protection subnet.

1.13 Deleting Isolated Nodes

To release protection resources that are used by isolated nodes, you need to delete isolated nodes.

1.1 Basic Concepts

According to the 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.

1.1.1 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, the

protection subnet is a generalized concept that includes not only the network architecture with

the comprehensive self-protection function, such as the MSP ring and PP ring, but also the

network architecture without the self-protection function, such as the non-protection ring and

non-protection chain.

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. It is independent from any protection

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, the

protection subnet is a generalized concept that includes not only the network architecture with

the comprehensive self-protection function, such as the MSP ring and PP ring, but also thenetwork architecture without the self-protection function, such as the non-protection ring and

non-protection chain.

In the U2000, a protection subnet is a network level concept rather than merely an MSP ring or

a PP ring. 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. It is independent from 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.

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 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.

Prerequisite

l You must be an NM user with "network maintainer" authority or higher.

l The NE data must be configured, and fibers must be properly created.

Procedure

Step 1 Choose Service > SDH Protection Subnet > Search for SDH Protection Subnet from the

Main Menu.

Step 2 In the Consistency Verification of Existing Subnet screen, select the protection subnet andclickNext.

NOTE

If the verification is unsuccessful and the subnet becomes abnormal, the search menu is unavailable. In

this case, you need to delete the abnormal subnet from the network layer and then re-search for the subnet.

Step 3 ClickSearch to start the search. The Subnet Name, Consistent Status and Subnet Typeparameters of the searched protection subnet are automatically displayed.

Step 4 ClickNext. The isolated nodes are displayed in the upper left pane of the window.

Step 5 Optional: Select the nodes that do not form any protection subnet, and clickDelete. ClickYes in the Operation Prompt dialog box.

Step 6 ClickFinish. The searched protection subnet is displayed in the Main Topology.

1.3 Configuring an MSP Ring

In a ring network topology or when a service exists between rings or between a ring and a chain,

you can configure an MSP ring to protect the service if a fault occurs.

1.3.1 Creating an MS Ring Protection SubnetThe MS ring protection scheme is adopted in a common ring network. Normally, it is adopted

to protect a channel to transmit additional services. By running the APS protocol, it achieves the

MS level protection.

1.3.2 Checking Networkwide Multiplex Section Parameters

In the same MSP subnet, each NE should have the same multiplex section parameter settings.

After configuring or adjusting an MSP subnet, you need to check the parameters for the

networkwide multiplex section.

1.3.3 Verifying MSP Protection Switching

After creating a protection scheme and setting the related parameters, you can check whether

the protection scheme functions normally by performing a switching operation and query theswitching status.

1.3.1 Creating an MS Ring Protection Subnet

The MS ring protection scheme is adopted in a common ring network. Normally, it is adopted

to protect a channel to transmit additional services. By running the APS protocol, it achieves the

MS level protection.

Prerequisite

l You must be an NM user with "network maintainer" authority or higher.

l The NE data must be configured, and fibers must be properly created.

Context

l The number of nodes in an MSP ring cannot exceed 16.

l When creating a protection subnet, select SDH NEs only. It is not required to select REG

or WDM equipment.

Procedure

Step 1 Choose Service > SDH Protection Subnet > Create 2f_MS SPRing from the Main Menu. ThePrompt dialog box is displayed. ClickOK.

NOTE

l To create a four-fiber bidirectional MS shared protection ring, choose Service > SDH Protection Subnet

> Create 4f_MS SPRing from the Main Menu to display the related dialog box.

l To create a two-fiber unidirectional MS shared protection ring, choose Service > SDH Protection

Subnet > Create 2f_MS DPRing from the Main Menu to display the related dialog box.

Step 2 Enter the name of the protection subnet. The default name is usually used, for example, 2f_MSSPRing_1.

Step 3 Select the rate of the protection subnet, for example, STM-4.





1-5


28/385

Step 4 Select Resource Sharing and Assigned by VC4 as needed.

NOTE

l Resource Sharing indicates that a port is mapped into multiple protection subnets. If multiple

protection subnets uses one port of a board, you need to check the Resource Sharing check box. If

different protection subnets use different ports of a board, do not check this check box. If MSP Sharing

is enabled, you can check the Resource Sharing check box to map a port of the board to multiple

MSPs.

l Select the Assigned by VC4 option when there are different VC4s belonging to different protection

subnets to achieve virtual optical path protection. For example, for an STM-16 fiber, the VC4 1-4

belong to an STM-4 MSP, and VC4 5-8 belong to a non-protection ring.

Step 5 Add nodes to the protection subnet to be created. Double-click the NE on the Main Topology

to add it to the node list in the left-hand pane. Meanwhile, is displayed on the NE icon. If you

want to cancel the selection, double-click the NE again.

NOTE

For easy maintenance, the nodes should be added anticlockwise to the protection subnet.

Step 6 Set the attribute of the nodes. Select MSP Node in this example.
