一种Web服务器集群的可伸缩管理算法

Scalable Algorithm for Management of Web Server Cluster

如何根据网络任务的忙闲变化,对Web服务器进行调度管理,是Web应用中面临的新问题之一。目前,由于追求为用户提供快速及时的应答服务,越来越多的系统采用了Web服务器集群技术。文中针对Web服务器的网络任务特点,以排队论为工具,提出了一种新的Web服务器集群管理算法。该算法通过调整服务器数目来增减处理能力,实现对Web服务器集群的可伸缩管理。

How to supervise Web server according to the variation of workload is one of new problems in application of Internet. In order to respond users on Internet punctually,more and more websites adopt the technology of web server cluster. This paper discusses the behavior property of network task on web server,proposes a new management algorithm for Web server cluster with the queuing theory. This algorithm realizes the scalable management of Web server cluster by adjusting the number of server.
