1. A method for providing answer message-based network management, the method comprising:
- receiving, at a Diameter signaling router (DSR), a first Diameter answer message from a first Diameter node, wherein the first Diameter answer message includes error indicator information, wherein the first Diameter answer message is transmitted by the first Diameter node in response to a request transmitted to the first Diameter node and wherein the error indicator information concerns status of the first Diameter node;
examining, at the DSR, the error indicator information included in the first Diameter answer message; and
using the error indicator information to update status information for routes maintained by the DSR to the first Diameter node.

Abstract
Methods, systems, and computer readable media for performing Diameter answer message-based network management at a Diameter signaling router (DSR) are disclosed. According to one method, a Diameter answer message that includes error indicator information is received from a first Diameter node at a DSR. The error indicator information included in the Diameter answer message is examined, at the DSR, and information based on the error indicator information is used to update status information for routes maintained by the DSR to the first Diameter node.
