Diameter Signaling Router (DSR): Request Message Processing Overview Including Application Routing Table and Peer Routing Table Selection Sequence (Doc ID 2472876.1)

Last updated on SEPTEMBER 20, 2022

Applies to:

Goal

The objective of this article is to outline the sequence in which DSR selects a provisioned Application Routing Table (ART) or Peer Routing Table (PRT) within the context of overall Diameter message processing through the Diameter configuration.  This will aid in the understanding of how the DSR processes an ingress Request message, and allow for more effective troubleshooting using the Diameter configuration information. 

The discussion is not at a detailed level, as additional depth is out of scope for a Knowledge article. 

The core of this information is valid from DSR 7.1 and later, subject to change.  Information provided may not be valid in all situations and is intended for general guidance.
