Excerpt
Introduction: This document describes the Diameter protocol application used for AAA in the Network Access Server (NAS) environment. When combined with the Diameter Base protocol [BASE], Transport Profile [DiamTrans], and EAP [DiamEAP] specifications, this Diameter NAS application specification satisfies NAS-related requirements defined in RFC 2989 [AAACriteria] and RFC 3169 [NASCriteria]. 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.
