Internet Engineering Task Force (IETF) B. Burman Request for Comments: 7728 A. Akram Updates: 5104 Ericsson Category: Standards Track R. Even ISSN: 2070-1721 Huawei Technologies M. Westerlund Ericsson February 2016 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. Status of This Memo This is an Internet Standards Track document. This document is a product of the Internet Engineering Task Force (IETF).
