Diameter Base Protocol
draft-ietf-dime-rfc3588bis-33.txt
Abstract
The Diameter base protocol is intended to provide an Authentication,
Authorization and Accounting (AAA) framework for applications such as
network access or IP mobility in both local and roaming situations.
This document specifies the message format, transport, error
reporting, accounting and security services used by all Diameter
applications. The Diameter base protocol as defined in this document
obsoletes RFC 3588 and RFC 5719 and must be supported by all new
Diameter implementations.
