Registering Values of the SDP 'proto' Field
for Transporting RTP Media over TCP under Various RTP Profiles
Abstract
The Real-time Transport Protocol (RTP) specification establishes a
registry of profile names for use by higher-level control protocols,
such as the Session Description Protocol (SDP), to refer to the
transport methods. This specification describes the following new
SDP transport protocol identifiers for transporting RTP Media over
TCP: 'TCP/RTP/AVPF', 'TCP/RTP/SAVP', 'TCP/RTP/SAVPF',
'TCP/DTLS/RTP/SAVP', 'TCP/DTLS/RTP/SAVPF', 'TCP/TLS/RTP/AVP', and
'TCP/TLS/RTP/AVPF'.

1. Overview
The Real-time Transport Protocol (RTP) provides end-to-end network
transport functions suitable for applications transmitting real-time
data such as audio or video over multicast or unicast network
services. The data transport is augmented by the RTP Control
Protocol (RTCP) to allow monitoring of the data delivery in a manner
scalable to large multicast networks and to provide minimal control
and identification functionality.
"SDP: Session Description Protocol" [RFC4566] provides a general-
purpose format for describing multimedia sessions in announcements or
invitations. "TCP-Based Media Transport in the Session Description
Protocol (SDP)" [RFC4145] specifies a general mechanism for
describing media transport over TCP using SDP with [RFC4571] defining
a method for framing RTP and RTCP packets [RFC3550] onto a
connection-oriented transport (such as TCP). "Connection-Oriented
Media Transport over the Transport Layer Security (TLS) Protocol in
the Session Description Protocol (SDP)" [RFC4572] extends [RFC4145]
for describing TCP-based media streams that are protected using TLS
[RFC5246].
This specification describes additional SDP transport protocol
identifiers for transporting RTP media over TCP as defined in
Section 3.
