摘　　要：针对IP组播和应用层组播的特点,将两者组合使用,提出一种基于分层组播的业务实现方案。在局域范围内形成若干IP组播域,在每个IP组播域内设置组播代理,数据源通过IP组播代理完成数据的转发,可有效地降低组播树的更新频率,减少组播造成的网络开销,同时提高组播业务流的可控性。This paper present a layered muhicast-based Realization of service on a common network. In the local net- work, IP muhieast is used, and an number of IP multicast domain are formed in the entire network. IP multieast agent is de- ployed in each IP muhicast domain. All agents a application multicast is built among all agents. The data sourse transmits data through the fountained agent, which can effectively decrease the number of muhicast updata frequency and reduce the overhead caused by muhicast. At the same time,it can prove the controllability of muhicast traffic stream.
