Method, system, and computer-readable medium for performing stateful Diameter routing with Diameter routing agents that use different mechanisms to achieve stateful routing

摘要

Disclosed are methods, systems, and computer-readable media for performing stateful routing with a Diameter routing agent (DRA) that uses different mechanisms to achieve stateful routing. According to one aspect, a system for performing stateful Diameter routing using DRA that uses different mechanisms to achieve stateful routing includes a series of Diameter signaling routing nodes. Each node has access to at least one database for maintaining state information. The node is configured to be a member of the first group, and each member of the first group has a first mechanism to achieve stateful routing with other members of the first group. And configured to use the second mechanism to achieve stateful routing with nodes that are not members of the first group. Members of the first group include signaling nodes provided by the same vendor, and members not in the group include signaling nodes provided by different vendors.
