Diameter is an authentication, authorization, and accounting protocol. used primarily for Service provider networks . It evolved from and replaces the much less capable RADIUS protocol that preceded it.
in this presentation I will try to familiarize you with the new AAA protocol and deep dive into the diameter protocol details, Credit Control Application (Gx,Gy and GZ) and sample use case for peering Sandvine PTS (Working as PCEF) with freePCRF.server and finally introduce you with seagull, a popular test tool to test different diameter-based scenarios
Hope You like it.
