基于宽带广域网的分布式多媒体服务系统

Broad Bandwidth WAN Based Distributed Multimedia Service System

服务器的系统结构是影响大规模MOD服务系统的性能和效率的主要因素。提出了一种可扩展的与分布式结构相似的服务器系统结构，并讨论了用IP Multicast 实现服务器系统的方法。利用该结构可以低成本构建大规模的MOD服务系统。

The architecture of server sub-system is most important to large-scale MOD service system, especially to the performance and efficiency of the service. This paper proposes a scalable and distributed-like architecture of the server sub-system. It also describes how to implement it with IP Multicast. Large-scale MOD service system can be constructed at a low cost with this architecture.
