网络视频流自适应拥塞控制技术的研究

Research for Video Streaming Adaptive Congestion Control Technique

针对当前IP网络拥塞控制问题,提出了视频流自适应拥塞控制技术,同时建立了实现该技术的框架。此技术综合了UDP与TCP的传输特性,能够对网络拥塞进行自适应控制,同时将该技术应用在一个端到端的视频传输系统中。实验结果表明,在实时性要求高的应用上可以为视频流提供良好的传输质量。

To solve the problem of congestion control in current IP netwok, the technique of network adaptive congestion control technique is proposed and the framework of his technique is given, and this technique integrates the characteristics of transmission on UDP and TCP, and ean control the network congestion adaptively. By applying the technique to the end to end video transmission system, the experimental result shows that this technique can provide better transmission quality in video streaming.
