摘　　要：讨论了使用应用层多源组播实现支持QoS参数定制多媒体交互性应用的一种路由构建算法。算法使用了多棵树的方式实现了多对多的组播关系构建。通过仿真试验比较分析得出结论:短时延优先策略可以提高系统成员的容纳能力,节点能力优先策略改进了系统的组播链路效率。To discuss the deployment of multi-source overlay multicast in a multimedia collaborative application which supports the customization of QoS. Multi-tree method is used when constructing the many to many multicast structure. Through the comparison and analysis about the simulation work, this paper comes to the conclusion that short-delay first member joining strategy improves the system capacity and node-ability first strategy improves the multicast efficiency.
