Diameter Base Protocol
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 it must be supported by
all new Diameter implementations.
