摘要： 首先分析了可靠组播拥塞控制机制所面临的问题,在此基础上提出了一个基于分级树的可靠组播的拥塞控制机制,它着重考虑了拥塞控制的可扩展性以及与TCP数据流的友好性,因而具有很强的实用性。仿真试验结果表明,该拥塞控制机制可以较好地解决TCP流对瓶颈带宽的共享问题,并在一定程度上满足了可靠组播流对TCP友好性的要求。

Abstract: First the paper analyzes the principal problems of congestion control for reliable multicast , then puts forward with a congestion control scheme of reliable multicast, in which the extendibility and the friendship with TCP data stream are concerned. The simulation result shows that the scheme can solve the problem of sharing the bottle-neck broadcast, and satisfy the request for TCP-friendship as well.
