多媒体多播应用在Internet上的广泛部署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 针对现有分层多播大多存在拥塞响应延时大、吞吐率抖动剧烈和不满足TCP友好的问题 ,提出一种新的基于主动网的分层多播拥塞控制方案 (ANLMCC) ,利用主动网灵活的服务定制能力 ,采用主动标记分层、优先级分层过滤 ,以及主动节点间逐跳的交互信令机制 ,大大改进了分层多播的性能 仿真实验表明 ,ANLMCC具有较快的拥塞响应速度、较好的稳定性和TCP友好的优点
Multimedia multicast applications on the Internet, the deployment of a wide range of multicast congestion control requirements Layered multicast is to adapt to network heterogeneity More effective solution to the existing hierarchical multicast Most congestion response delay large, throughput jitter Violently and not satisfied with the TCP-friendly problem, a new active multicast-based hierarchical multicast congestion control scheme (ANLMCC) is proposed, which utilizes the flexible service customization capability of the active network, adopts active label layering, priority layering filtering, And hop-by-hop interactive signaling mechanism between active nodes, which greatly improves the performance of hierarchical multicast simulation experiments show that ANLMCC has a faster congestion response speed, better stability and TCP-friendly advantages
