2.19 Diameter Egress Throttle Groups

Egress Throttle Groups are used to monitor egress Request rate and pending transactions for multiple Peers and Connections across multiple DA-MPs. If a Peer is assigned to the Egress Throttle Group, then all Diameter Connections to that peer are implicitly part of the Egress Throttle Group.

You can perform these tasks on an Active System OAM (SOAM).

Egress Throttle Group functions are described in detail in Egress Throttle Groups. Egress Throttle Groups control the following functions.

An Egress Throttle Group can be standalone, or it can be associated with an Egress Throttle List that spans multiple signaling routers. An Egress Throttle Group can be associated with only one Egress Throttle List. See Diameter Egress Throttle List.

• Egress Throttle Group Rate Limiting controls the total egress Request traffic that is routed to a configured group of Peers or Connections.
• Egress Throttle Group Pending Transaction Limiting controls the number of pending transactions that are allowed for a configured group of Peers or Connections.
• The Egress Throttle Group Rate Limiting and Egress Throttle Group Pending Transaction Limiting provide egress throttling capability that enables:
  • A group of Peers and Connections to be associated with an Egress Throttle Group
  • The maximum egress Request rate of Egress Throttle Groups to be set
  • The maximum pending transaction limit of Egress Throttle Groups to be set
  • The Egress Throttling Control Scope.

On the Diameter, and then Configuration, and then Egress Throttle Groups page, the following actions can be performed:

• Filter the list of Egress Throttle Groups to display only the desired Egress Throttle Groups.
• Sort the list by a column in ascending or descending order by clicking the column heading.

  The default order is by Egress Throttle Groups Name in ascending ASCII order.

• Click Insert.

  On the Diameter, and then Configuration, and then Egress Throttle Groups [Insert] page, you can add new Egress Throttle Groups.

  The Diameter, and then Configuration, and then Egress Throttle Groups [Insert] page does not appear if the maximum number of Egress Throttle Groups (128 per NE) already exists in the system.

• Select an Egress Throttle Group in the list and click Edit.

  On the Diameter, and then Configuration, and then Egress Throttle Groups [Edit] page, you can edit the selected Egress Throttle Group.

  If the selected Egress Throttle Group has been deleted by another user, then the Diameter, and then Configuration, and then Egress Throttle Groups [Edit] page does not open.

• Select an Egress Throttle Group in the list and click Delete to delete the selected Egress Throttle Group.
