摘　　要：提出了一个基于应用层的多源组播协议ALMSM。ALMSM协议是针对小规模的多源视频会议而设计的,是一个完全分布式系统,除"主成员"外所有成员是逻辑平等的且包含一个完整的成员列表,"主成员"则包含带宽、延迟和负载信息,决定何时优化多播树。给出了"主成员"的设计及协议的主要算法。This paper proposed a multi - sources multicast protocal based on application layer named ALMSM which tailored to small - scale video conference. It is a fully distributed system. All the members expect the main member are equal;each end has a complete memberlist. The ＂key member＂ has the sources of band- width,end to end delay and load ,and control of multicast tree. This paper described the method of ＂key member＂ and major algorithms.
