Abstract

   This document describes a protocol for carrying accounting
   information between a Network Access Server and a shared Accounting
   Server.

Implementation Note

   This memo documents the RADIUS Accounting protocol.  The early
   deployment of RADIUS Accounting was done using UDP port number 1646,
   which conflicts with the "sa-msg-port" service.  The officially
   assigned port number for RADIUS Accounting is 1813.
