摘要:

在实时传输控制协议(RTCP)扩展协议基础上提出了适用于特定源端组播应用的RTCP控制框架。该控制框架支持RTCP扩展前后2种版本共存,且在大规模组播应用中能有效减小反馈流量对核心网络资源的占用,并能提高源端响应网络拥塞的速度。

关键词: 特定源端组播, 拥塞反馈速度, 拥塞响应时间

Abstract:

Based on the characteristics of RTCP (real-time transport control protocol) extension, an extensible RTCP control framework designed for source specific multicast applications was proposed. In contrast to traditional control framework, the framework mentioned here could efficiently reduce the usage of network resources that the RTCP traffic would consume. In the meantime, it can feed back the QoS information to sender in time, so that the sender can raise the network congestion response time.

Key words: source specific multicast, congestion feedback speed, congestion response time
