Internet Society Requests For Comment (RFCs)
The RADIUS protocol is defined in [RFC2865] as using the User Datagram Protocol (UDP) for the underlying transport layer. While there are a number of benefits to using UDP as outlined in [RFC2865], Section 2.4, there are also some limitations:

RADIUS over TCP
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.
