Diameter Route Lists

A Route List is a user-configured set of Route Groups used to determine the distribution of traffic between each Route Group within the Route List. Each Route List can include up to three Route Groups.

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

Traffic distribution to a Route Group is based on its available capacity and assigned priority within the Route List. A Route Group with a priority of 1 has the highest priority and a Route Group with a priority of 3 has the lowest priority.

Only one Route Group in a Route List is designated as the active Route Group for routing messages for that Route List. The other Route Groups in the Route List function as standby Route Groups. The active Route Group in each Route List is determined based on the Route Group's priority and its capacity relative to the configured minimum capacity of the Route List.

When the Operational Status of Peer Nodes assigned to the active Route Group changes, or the configuration of either the Route List or Route Groups in the Route List changes, then the designated active Route Group for the Route List may change.

Route Lists are assigned to Peer Routing Rules. When a Diameter message matches a Peer Routing Rule, the Route List assigned to the Peer Routing Rule directs the Diameter message to a Peer Node in the active Route Group.

Route Lists are assigned to Peer Nodes when Alternate Implicit Routing is used.

Route Lists are assigned to Message Copy Configuration Sets to be used for copying a message to a DAS node.

On the Diameter > Configuration > Route Lists page, you can perform the following actions:

• Filter the list of Route Lists to display only the desired Route Lists.
• Sort the list by the Route List Name column or the Minimum Route Group Availability Weight column in ascending or descending order by clicking the column heading. The default order is by Route List Name in ascending ASCII order. The expanded rows of Route Groups are sorted by Priority.

• Click an entry that is shown in blue for a Route Group (in the expanded list).

• Click Insert.

  On the Diameter > Configuration > Route Groups [Insert] page, you can add a new Route List.

  The Diameter > Configuration > Route Groups [Insert] page does not open if :

  • The maximum number of Route Lists (2000) already exists in the system
  • There is no available Route Group

• Select a Route List in the list and click Edit.

  On the Diameter > Configuration > Route Lists [Edit] page, you can edit the selected Route List.

  If the selected Route List has been deleted by another user, the Diameter > Configuration > Route Lists [Edit] page does not open.

• Select a Route List in the list and click Delete. You can delete the selected Route List.
