| 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. |
