基于Internet的多媒体多播应用的迅猛发展对多播拥塞控制提出了要求.分层多播是适应网络异构性较有效的方案.针对现有分层多播存在的问题
将主动网技术思想引入到分层多播拥塞控制中
提出了一种逐跳TCP友好的主动分层多播拥塞控制方案(HTLMA)
采用主动标记分层、逐跳探测TCP友好可用带宽
以及主动速率控制机制.仿真实验表明
HTLMA方案大大改进了分层多播拥塞控制的性能
具有较快的拥塞响应速度、较好的稳定性和TCP友好特性.
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.
