| 摘 要： | 域间组播一直是大范围内部署组播时需要考虑的主要因素。依赖源汇聚点组播是一种基于Chord查找协议的简单有效的域间组播方案，方案中接收者的指定路由器（DR）使用Chord协议获得源RP地址，并加入源RP树。依赖源汇聚点的组播方案是一种域同ASM解决方案；能提供很好的容错性和可扩展性；支持主机移动组播，但不会造成三角路由问题。

| Abstract: | The key factor in wide-scale multicast deployments is the inter-domain multicast. Source rendezvous point dependent multicast is a simple but effective inter-domain multicast scheme based on the Chord lookup protocol. In this scheme the receiver's designated router (DR) will discover the address of the rendezvous point (RP) in the source register by using the Chord protocol, and is thus joined to the multicast tree passing through this rendezvous point. The source rendezvous point dependent multicast scheme is an inter-domain multicast solution using Any Source Multicast (ASM), which has good fault tolerance and expandability, and provides multicast support for mobile hosts without incurring triangular routing. |
