RTP Stream Pause and Resume
Abstract
With the increased popularity of real-time multimedia applications,
it is desirable to provide good control of resource usage, and users
also demand more control over communication sessions. This document
describes how a receiver in a multimedia conversation can pause and
resume incoming data from a sender by sending real-time feedback
messages when using the Real-time Transport Protocol (RTP) for real-
time data transport. This document extends the Codec Control Message
(CCM) RTP Control Protocol (RTCP) feedback package by explicitly
allowing and describing specific use of existing CCMs and adding a
group of new real-time feedback messages used to pause and resume RTP
data streams. This document updates RFC 5104.
