                      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.
