Research on network-based rate control mechanism for layered multicast
Zhiping Chen · Journal of China Institute of Communications · 2002
This paper proposes a new rate control mechanism for layered multicast on the base of video layered coding and layered transmission protocol by combining the network_based and the receivers control mechanisms . The congestion is detected by both receivers and routers and the popularity of the session is weighted by routers so as to add or drop layers with fairness. The experiment results show that the mechanism can respond to congestion quickly and, making use of the most of bandwidth, provide better service quality for high popular sessions.
