Abstract

With the advent of 4G and beyond networks, the Authentication, Authorization and Accounting protocols face new challenges and have to adapt accordingly. In the legacy networks, the deployment of AAA protocol (Radius) required static configuration of the routing information in the AAA nodes. This poses bottleneck in advanced networks where signaling is going to be many folds compared to the actual data. The Diameter protocol, successor to the Radius protocol and being the future AAA protocol, has the option of dynamic discovery of other nodes. This thesis work suggests and investigates the extended Name Authority Pointer (NAPTR) as a method for discovering Diameter agents with support for specific applications and evaluates the results.
