Overview

Describes the functionality of service aggregations. Explains the specific benefits and underlying principles of this essential feature for improving overall system efficiency and operational management.

A service aggregation is a network feature that

  • enables two or more services to share the same trunk port or channel,

  • automatically groups services into a DefaultGroup within the network tree for efficient management, and

  • provides the ability to export aggregation reports for monitoring and analysis.

Feature Description

Services Aggregation

Cisco ONP Release 4.1

The services aggregation feature allows two or more services to share the same trunk port or channel. By default, the services are added to the DefaultGroup. You can export aggregation reports.

You can use services aggregation to allow multiple services to share the same connection point, such as a trunk port or channel. This ability to share is determined by the characteristics defined in their Service Group.

Specifically, when you add services to a 1K-2K-4K Traffic site within an SSON network, the system automatically creates a DefaultGroup under Services in the network tree. All the services you add are then automatically associated with DefaultGroup.

Create a new service group

Follow these steps to create a new service group.

Before you begin

Log in to the Cisco ONP web interface

Procedure

1.

Open the network where you want to create a new service group.

2.

Click the Ellipsis icon on the right side of Services under the network tree and choose Create Service Group.

A new service group appears under Services.

Modify service group properties

Follow these steps to modify the properties of a service group.

Before you begin

Log in to the Cisco ONP web interface.

Procedure

1.

Open the network where you want to modify the service group properties.
2.

Choose Network > Entity Editor.
3.

In the Entity Editor window, click the Services tab, and click a service group.
4.

Modify the service group properties as required.

See Service group properties.
5.

Click Update.

Service group properties

This table describes various service group properties.

Description

Available options

Default option

General

Name

NCS 2000

Displays the group name. Edit the name if needed.

â€â€

By default, the service name is based on the source and destination sites and the number of services between them.

For example, if there are two services between site 1 and site 2, the name of the services are Site-1-Site-2-1 and Site-1-Site-2-2, respectively.

Demand Types

NCS 2000

Select the demand type. For default group all demand types are available, and you cannot edit them.

â€â€

â€â€

Default Group

NCS 2000

Indicates whether the service group is a default group or a user created group.

â€â€

â€â€

NCS 4 K

Exclusive LC Usage

NCS 4000

Indicates whether the services belonging to this group must have an exclusive Line Card (LC).

For example, when you check this check box, neither the Client LC nor the Trunk LC of the services belonging to this group can be shared by services belonging to any other groups.

â€â€

â€â€

Symmetric Aggregation

NCS 4000

Indicates whether this group allows aggregation of only symmetric services. Services are symmetric if they have same protection scheme. Following are the various protection schemes:

For Example, all “1+1†services are symmetrical.

If you check this check box, this service group allows aggregation of only symmetrical services.

For example, “Unprotected†can be aggregated only with “Unprotectedâ€Â, “1+R†only with “1+Râ€Â, “1+1†only with “1+1â€Â, and so on.

If this check box is unchecked, this service group allows aggregation of symmetrical and unsymmetrical services together.

For example, “Unprotected†can be aggregated with either “Unprotectedâ€Â, “1+Râ€Â, “1+1†“1+1+R†or “1+1+R+Râ€Â.

See Rules for aggregating services.

Rules for aggregating services

These rules must be satisfied for any two services, whether symmetrical or non-symmetrical, to be aggregated:

  1. Both services must have identical source and destination points.

  2. The paths of the two services must align for the same path types.

    • Example for symmetric aggregation:

      When aggregating two "1+1" services, the working path of the first service must match the working path of the second service, and similarly, the protection paths of both services must also match.

    • Example for non-symmetric aggregation:

      When aggregating a "1+1" service with a "1+1+R" service, the working path and protection path of the first service must match the corresponding paths of the second service. However, the restoration path of the second service can differ.

  3. Both services must use the same wavelength for the same path types.

    • If the wavelength is set to "auto," it can be aggregated with either another "auto" wavelength or a fixed wavelength.

  4. Both services must have the same trunk mode configuration for the same path types.

  5. The regeneration sites for both services must align for the same path types.

  6. The demand type is not a constraint for aggregation, except when considering trunk capacity availability.

Associate a service with the newly created group

By default, the services are associated with the DefaultGroup. However, you can change the group.

Follow these steps to associate a service to the newly created group.

Before you begin

Log in to the Cisco ONP web interface.

Procedure

1.

In the network tree, click the service that you want to associate to a group.

You can view the properties of the network at the bottom of the network tree.
2.

Selct the group from the Service Group drop-down list.
3.

Click Update.

Note

For an LNI-imported network, all services are in the Default group by default. When you upgrade the LNI-imported network for the first time, you can move the services to other newly created Service Groups without unlocking them. For later upgrades, unlock the services before moving them between Service Groups. The Service Groups stay locked during upgrade mode unless you perform a complete network-level unlock.

Export aggregation reports

Follow these steps to export the service aggregation reports.

Before you begin

Log in to the Cisco ONP web interface.

Procedure

1.

Open an analyzed network to export the aggregation reports.
2.

Choose Export > Service Aggregation.
3.

Save the aggregation report as an Excel file to your local system.
