Effective multicast congestion control mechanism is urgently needed with the deployment of multimedia multicast applications in Internet.Layered multicast is considered to be an efficient approach to cope with the network heterogeneity.Receiver-driven layered multicast schemes have many disadvantages,such as large congestion response delay,unstable throughput and unfriendly bandwidth sharing with TCP.A novel congestion control scheme for layered multicast,called Hop-by-Hop TCP-friendly Congestion Control for Layered Multicast based on Active Network scheme (HTLMA),is proposed through introducing active label layering,hop-by-hop detecting TCP-friendly available bandwidth and active rate control mechanisms.Simulation results show that HTLMA is more responsive,more stable and TCP-friendly,and can improve the performance of layered multicast congestion control effectively.
