摘　　要：提出了基于集群的流媒体缓存代理服务器体系结构,并将基于内容的前端机负载平衡调度策略引入到流媒体缓存代理服务器的架构设计中,对系统设计原理及各组成模块结构和各模块间的消息通信机制进行了详细的分析阐述,主要采用C和C++语言在Linux操作系统下实现了原型系统,通过对原型系统进行测试,表明整个系统设计合理,性能突出,具有良好的稳定性和可扩展性。The architecture of the duster-based streaming caching proxy server was proposed, and content-aware scheduling mechanism was adopted to improve the performance of the scheduling in the duster. In addition, the designing principle as well as the modules and the communication mechanism among them were addressed in detail. The system was implemented under Linux platform by C and C ＋ ＋ language and tested through simulation testing method. From the testing results, it can be confirmed that the whole system is well designed which achieves high performance, good robustness and high scalability.
