RADIUS over TCP
RFC 6613, “RADIUS over TCP”, is an Experimental document published in May 2012 by A. DeKok. It has since been updated by RFC 7930, RFC 9765. The canonical text is published by the RFC Editor.
Abstract
The Remote Authentication Dial-In User Server (RADIUS) protocol has, until now, required the User Datagram Protocol (UDP) as the underlying transport layer. This document defines RADIUS over the Transmission Control Protocol (RADIUS/TCP), in order to address handling issues related to RADIUS over Transport Layer Security (RADIUS/TLS). It permits TCP to be used as a transport protocol for RADIUS only when a transport layer such as TLS or IPsec provides confidentiality and security. This document defines an Experimental Protocol for the Internet community.
What “Experimental” means
Describes a specification that is part of a research or development effort, published so the community can gain experience with it.
