Adaptive multicast in heterogeneous network environment
Wan Liu · Journal of Minjiang University · 2009
The application-level multicast is widely applied in internet and the past IP multicast is limited in network island.In order to resolve the problems of heterogeneous network environment,such as network heterogeneity and real-time transmission etc.,this paper proposes an agent-based adaptive multicast system,i.e.,the so-called AALM system(agent-based application-level multicast).Its basic idea is that AALM uses efficiently data transmission of IP multicast in LAN,one agent server is set in every IP multicast area,the backbone network composed of agents transmits data using application-level multicast.At the same time,AALM provides the module graph of system and the definition of transmission protocol table which demonstrates that AALM system can satisfy every different application requirement,save many network resources and improve the media service quality in heterogeneous environment.
