IESG Note:

This protocol is widely implemented and used. Experience has shown that it can suffer degraded performance and lost data when used in large scale systems, in part because it does not include provisions for congestion control. Readers of this document may find it beneficial to track the progress of the IETF’s AAA working group, which may develop a successor protocol that better addresses the scaling and congestion control issues.

Abstract

This document describes a protocol for carrying authentication, authorization, and configuration information between a Network Access Server which desires to authenticate its links and a shared Authentication Server.

Implementation Note

This memo documents the RADIUS protocol. The early deployment of RADIUS was done using UDP port number 1645, which conflicts with the "datametrics" service. The officially assigned port number for RADIUS is 1812.
