Diameter:: is an "AAA" (Authorization, Authentication and Accounting) protocol. It is a client/server protocol, used for handling service requests such as: *subscriber validation *network resource control *wireless mobility/roaming *charging and billing applications. Diameter is already widely deployed, and this is set to continue. The 3GPP, 3GPP2 and TISPAN groups have made Diameter their protocol of choice for subscription, policy and charging function in IMS and other next-generation network architectures. The Diameter protocol is an IETF standard, RFC 3588. This standard is known as the Diameter base protocol. It defines transport and session level management and support for basic accounting applications. Many application extensions are defined by standards bodies (including the IETF and 3GPP), and other extensions are created by vendors to support their proprietary AAA requirements. Diameter is upwardly compatible with RADIUS and, as its name suggests, was developed to address many of the limitations of RADIUS and fulfill the needs of modern AAA applications in next-generation networks. heba
