Abstract: This paper optimizes the traditional scheme to ensure the peak service of hot video objects by researching the clients’ accessing pattern to popular video objects, and designs a high performance cluster video server to ensure the peak service of hot video objects. It discusses the architecture and module functionality of the system, and provides the processing of software implementation. Test results show that the hot video concurrent threshold between 80 and 100 is appropriate.

摘要： 通过研究用户对热点对象的访问模式，优化传统的保障热点影片峰值服务的调度算法，设计一种对热点影片具有峰值服务保障能力的高性能视频服务器集群系统，论述系统体系结构和各模块的功能，给出软件实现的基本过程。实验表明，热点影片的并发量阈值设定在80~100之间较为合适。
