基于RTP/RTCP的网络视频拥塞控制研究

Research on Congestion Control of Network Video Based on RTP/RTCP

摘要: 随着流媒体实时传输技术和网络视频应用的迅猛发展，视频流量已成为网络流量的主要贡献者。然而有限的网络带宽导致流媒体实时传输过程中网络视频拥塞问题越来越受到人们的关注。本文通过对流媒体传输框架下RTP视频的深入研究，在其理论基础上研究出了一套针对RTP视频流的RTCP拥塞策略，并在测试环境下验证了该策略的可行性。

Abstract: With the rapid development of real-time transmission technology and the application of network video of the streaming media, video traffic has become the main contributor of network traffic. However, due to the limited bandwidth of the network, more and more people pay attention to the problem of network video congestion in the process of real-time transmission of streaming media. In this paper, through the in-depth study of RTP video in the framework of the streaming media transmission, based on its theory, a set of RTCP congestion strategies for RTP video stream is studied, and the feasibility of the strategy is verified in the test environment.
