Abstract

Abstract: On the basis of web-server control clusters with QoS, based on L4/L7 switching, a mixed load balance strategy is designed, which takes into account content of request, server performance and overall equilibrium state of the cluster load. Algorithm introduces a feedback loop which dynamically adjusts the weights of servers, by choosing different strategy according to thresholds of load balance, the performance of the Web cluster system is promoted.

Key words: quality of service, Web server, request dispatching, load balancing

摘要： 在对服务器集群Web QoS控制基础上，综合考虑请求内容和各服务器性能以及当前整个集群负载平衡状况，设计了一种基于L4/L7双层分配的混合负载平衡调度策略，算法引入了一个反馈环节动态地改变Web服务器的权值，通过负载平衡程度的阈值进行判断，选择不同的调度策略，从而提高了Web集群系统的性能。

关键词: 服务质量（QoS）, Web服务器, 请求分配, 负载平衡
