> 中文摘要: 为了有效地提高WWW服务器的吞吐能力、反应速度和可扩展性,国际上许多著名站点纷纷转向采用WWW集群服务器来替代原有的单一主机服务器.采用不同副本分布方式的WWW集群服务器,其数据可靠性也有所不同.对不同数据副本分布方式进行探讨,同时,论证了最优副本分布方案.
Abstract: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.
