RTP and the Datagram Congestion Control Protocol (DCCP)
Abstract
The Real-time Transport Protocol (RTP) is a widely used transport for
real-time multimedia on IP networks. The Datagram Congestion Control
Protocol (DCCP) is a transport protocol that provides desirable
services for real-time applications. This memo specifies a mapping
of RTP onto DCCP, along with associated signalling, such that real-
time applications can make use of the services provided by DCCP.

RFC 5762 RTP over DCCP April 2010
1. Introduction
The Real-time Transport Protocol (RTP) [1] is widely used in video
streaming, telephony, and other real-time networked applications.
RTP can run over a range of lower-layer transport protocols, and the
