摘　　要：域间组播是大范围内部署组播时需要考虑的主要因素。该文提出了一种基于Chord查找协议的简单有效的域间组播方案。该方案具有良好的扩展性和负载平衡性,能够很好地支持任意源组播(ASM),并为主机移动组播提供了方便。不仅描述了该组播方案的构建,还分析了该方案所具有的特点及其自身的安全特性。A fundamental factor of multicast deployment in wide area network is inter-domain multicast. A simple, useful inter-domain muldcast architecture is constructed. It is named Any-to-Any （A2A） multicast, which means that it applies to any source multicast. Using Chord and P1M-SM as the basic protocols, A2A multicast has many good features such as well scalability, failover, and load-balancing. While supporting ASM very well, it is helpful for host mobile multicast. The architecture is described, and features and security issues pertaining to it are discussed.
