摘　　要：提出一种新的基于代理的系统——应用层自适应多播AALM系统,改善网络的异构性和传输实时性。在局域范围内采用高效率的IP multicast进行数据传输,每个多播域中设置一个代理服务器MAN,MAN之间的主干网络通过应用层多播进行数据传输,实现在Internet范围内的多点数据通信。采用了XML驱动的服务定制机制,可以满足不同应用需求,节省大量的网络资源,提供网络吞吐量,提高视频服务质量。An agent-based multicast application （AALM） system was adopted to improve network heterogeneity and real-time control. An agent server named MAN was set in every IP multieast area. Data was transmitted between the MANs using application-level multicast. The transmission of many nodes in the Intemet was realized. A service subscribing mechanism in XML format was employed in AALM. The results show that AALM can save network resources, increase network accessibility and improve video service quality.
