Selecting Peer Node Application Route Tables

Use this task to select Peer Node Application Route Tables.

1. Click Diameter > Configuration > Peer Nodes.
2. Select the Application Route Table for this Peer Node.
   Select the Application Route Table as per the following precedence selection criterion, highest to lowest priority.

   • This only applies when the Request message was received from a routing application. The ART is provided by the application via an Application-Data stack event parameter if it exists.
   • If the message is a Redirected Request, the ART provided by System Options > Redirect Application Route Table is used if it exists. As described here, when the message is a Redirected Request, the DRL selects the configured System Options > Redirect Application Route Table. If it is not configured, no ART is searched (ART processing skipped).
   • The ART provided by an Application Routing Rule with an action of Forward to ART if it exists.
   • Otherwise:
     • If Transaction Configuration Set is selected on the ingress Peer Node from which the Diameter Request was received, use Transaction Configuration Set and apply longest/strongest match search criteria for Diameter Request message parameters comparison and if a match is found, the ART assigned to the Transaction Configuration Rule defined under this Transaction Configuration Set is applied if it exists.
     • The ART assigned to the ingress Peer Node from which the Request message was received if it exists.
     • Search Default TCS and apply longest/strongest match. Use ART associated with best match if any is found.
     • Default ART.
