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
