Research on Distribution of Data Copy for WWW Server Clusters
WWW集群服务器的数据副本分布方式研究

In order to improve the throughput, response speed and scalability of Web servers efficiently, many famous Web sites have thrown away single servers and turned to Web server clusters. Web server clusters with different distribution modes of data copy have different data availability levels. After discussing many data copy distribution modes, an optimized data copy distribution is proved in this paper.
