Abstract
This document describes the Diameter protocol application used for
Authentication, Authorization, and Accounting (AAA) services in the
Network Access Server (NAS) environment. When combined with the
Diameter Base protocol, Transport Profile, and Extensible
Authentication Protocol specifications, this application
specification satisfies typical network access services requirements.
Initial deployments of the Diameter protocol are expected to include
legacy systems. Therefore, this application has been carefully
designed to ease the burden of protocol conversion between RADIUS and
Diameter. This is achieved by including the RADIUS attribute space
to eliminate the need to perform many attribute translations.
The interactions between Diameter applications and RADIUS specified
in this document are to be applied to all Diameter applications. In
this sense, this document extends the Base Diameter protocol.
