摘　　要：在用应用层组播和IP组播技术基础之上,提出了一种新的网络拓扑结构,用以改善当前流行的基于P2P的流媒体传输技术所存在的时延,不易管理及控制难等问题。针对这些问题对此改进技术的实现方法进行了深入的分析和研究,并在一定的网络环境下进行了相关的测试实验,并对测试结果进行了综合评价。Based upon Application Layer Multicast and IP Multicast Technology, the transmission of the existing P2P Multimedia is improved which has some disadvantages such as time delay in tdfransmission, difficulties of control and management in Multicast Group members. Furthermore, the implementation of the improved method. Lastly, a test in the new net topology and a comprehensive assessment in its test results are given.
