               Diameter Network Access Server Application
                     draft-ietf-dime-rfc4005bis-07

Abstract

   This document describes the Diameter protocol application used for
   Authentication, Authorization, and Accounting (AAA) services in the
   Network Access Server (NAS) environment; it obsoletes RFC 4005.  When
   combined with the Diameter Base protocol, Transport Profile, and
   Extensible Authentication Protocol specifications, this application
   specification satisfies typical network access services requirements.
