Configuring SRC-ACP to Manage the Backbone Network

To configure SRC-ACP to manage the backbone network, you must:

  1. Configure network interfaces that represent locations of congestion points in the directory.
  2. (Optional) Configure an action congestion point.
  3. Configure guaranteed bandwidths for services.
  4. Assign network interfaces to services.
  5. Create congestion points in the directory.
  6. Assign network interfaces to congestion points.

Configuring Network Interfaces in the Directory (Backbone Network)

You configure network interfaces in the directory in the same way for edge and backbone congestion points. However, for backbone congestion points, you can add only VRs and their interfaces. For information about this procedure, see Configuring Network Interfaces in the Directory (Edge Network).

Extending SRC-ACP Congestion Points

You can extend SRC-ACP congestion points to initialize and execute applications defined in a backbone congestion point. SRC-ACP provides a service provider interface (SPI) to:

The SPI for ACP provides a Java interface that a congestion point application implements. For information about the SPI for ACP, see the documentation in the SRC application library distribution in the folder SDK/doc/acp.

The implementation of the SPI for ACP can be a customized application that performs certain tasks, such as creating or removing congestion points on the router. SRC-ACP acts as an interface tracking plug-in, and interface tracking events are treated as remote updates for congestion points when they are created, modified, or removed.

SRC-ACP supports applications written in Java or Jython. For scripts written in Java, you must compile and package the implemented SPI for ACP to make it available for use by SRC-ACP. A Java implementation can include more than one Java archive (JAR) file.

To use congestion point applications with SRC-ACP, configure an action congestion point that references the script (see Configuring Action Congestion Points).

Configuring Action Congestion Points

You can define an application in a backbone congestion point so that SRC-ACP can execute it in a predefined manner. Backbone congestion points that are configured to run an application are called action congestion points. If you want to use an action congestion point to execute an application that requires real-time congestion point status, you must enable SRC-ACP state synchronization with the SAE (see Configuring SRC-ACP Redundancy).

Before you configure an action congestion point, make sure that you know the location of the application file.

To configure an action congestion point:

  1. Click Configure>Shared, and expand Service.
  2. In the side pane, expand the desired retailer, and then click the desired subscriber folder.

The Admission Control pane appears.

  1. Enter information in the Congestion Points box as described in the Help text in the main pane, and click Apply.

Configuring Bandwidths for Services (Backbone Network)

You configure bandwidths for services in the same way for edge and backbone congestion points. For information about this procedure, see Configuring Bandwidths for Services.

Configuring Congestion Points for Services

You must assign a congestion point to each service that SRC-ACP manages.

To configure values for services:

  1. For global configuration, click Configure>Services>Global and expand Service.
  2. For scope configuration, click Configure>Services>Scope and expand Service.
  3. In the side pane, expand the desired service, and click Admission Control.

The Admission Control pane appears.

  1. Enter information as described in the Help text in the main pane, and click Apply.

Configuring Congestion Points in the Directory

To configure individual backbone congestion points:

  1. Click Configure>Shared>Congestion Points.

The Congestion Points pane appears.

  1. In the Create new list, select Profile. Type a name for the new profile in the dialog box, and click OK.

The Congestion Point Profile screen appears.

  1. Enter information as described in the Help text in the main pane, and click Apply.

Assigning Interfaces to Congestion Points

You must assign interfaces either to VRs or to individual services under the VRs. Services inherit interface assignments from the associated VR unless you assign an interface to the individual service. This network interface lists the DNs of interfaces associated with backbone congestion points.

To assign interfaces to congestion points:

  1. Click Configure>Shared>Congestion Points.
  2. In the side pane, expand the desired profile.

The Profile pane appears.

  1. Enter information as described in the Help text in the main pane, and click Apply.
