视频在互联网上的实时传输常因其要求高带宽、低延迟而造成网络拥塞。传统TCP基于窗口的拥塞控制已经不适用于实时传输中的拥塞控制,该文讨论了基于速率的网络拥塞控制方法,它采用自适应码率和分层的视频编码技术,详细说明了基于源端和收端的各种速率控制方法。
Real-time transmission of video on the Internet often because of its high bandwidth, low latency caused by network congestion. The traditional TCP-based congestion control is not suitable for congestion control in real-time transmission. This paper discusses the rate-based network congestion control method, which uses adaptive rate and layered video coding technology, And closing a variety of rate control methods.
