分布式多媒体点播系统的结构设计

摘要

There are many difficulties in realizing a large scale Media onDemand (MOD) system. This paper analyzes the service models in a MOD system and constructs a distributed MOD system with high performance. It can be widely used in many kinds of interactive multimedia services, such as VOD etc.%实现大规模可扩展的多媒体点播系统一直存在许多困难.本文通过对多媒体点播系统中服务模型的分析，设计了可扩展的分布式多媒体点播系统.在媒体服务器的结构设计方面，采用了中央调度的多层服务器结构，保证了系统的性能.
