Layered Multicast Congestion Control Mechanism Based on DiffServ
Liu Feng-yu · Journal of Chinese Computer Systems · 2010
Network heterogeneous problems is more outstanding with the development of multimedia applications in Internet,and it calls for new demand for traditional multicast congestion control,layered multicast is considered to be an efficient approach to cope with the network heterogeneity.To conquer the problems of quality instability,control complexity,and frequent changes of multicast tree in traditional layered multicast,a layered multicast congestion control mechanism base on DiffServ called LMCC is proposed.It marks and forwards the packets on the premise of the fairness reserving of bandwidth,so it adapts the heterogeneous network well.Simulation results show that LMCC characterizes with more responsive,more stable,better TCP-Friendliness and low loss rate.
