Diameter Network Access Server Application
RFC 4005, “Diameter Network Access Server Application”, is a Proposed Standard document published in August 2005 by P. Calhoun, G. Zorn, D. Spence, D. Mitton. It has been obsoleted by RFC 7155 — refer to the newer document for the authoritative version. The canonical text is published by the RFC Editor.
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. [STANDARDS-TRACK]
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
