摘要
目前因特网协议（ＩＰ）组播路由协议在结构上可分为基于源和基于组的两类转发树结构．把这两种组播路由结构在扩展性能、对单播路由算法的依赖性、业务量拥塞特性、网络的额外开支量以及对源ＩＰ地址的依赖性等方面进行分析比较，指出它们在不同应用场合的优缺点，为两种结构的路由协议相互结合。
The presentIPm ulticastrouting protocols can be classified into two categories in architecture: source based tree architecture and group based tree architecture. This paper analyzed and com pared the tw o architectures in their scalability, dependence on unicast routing protocols, traffic concentration, am ountofoverhead and dependence on IPsource address. Theiradvantagesand disadvantagesin kinds of applications were analyzed, w hich givesthebasisforintegration ofrouting protocolsbelonging to different architecture.
