摘　　要：Web服务器集群是提高HTTP请求处理能力的重要途径,但是请求负载的增加常常导致Web服务器集群性能降低,用户期望的服务质量得不到保证。针对这种情况,提出了通过采用对用户请求分类和请求许可控制的策略,对不同类别的Web请求提供不同质量的服务,保证服务级用户的服务质量。仿真实验表示明,这种策略能改善系统的负载均衡能力,缩短系统平均响应时间。The increase of requests often results in performance degradation of the web server cluster. The quality of service (QoS) expected by users can't be guaranteed. This is the problem that service-level web server cluster must cope with. In this paper, two strategies are proposed including classification of the user requests and request admission control, the different quality of service can be reached and the QoS of service-level users is guaranteed. The simulation experiments proved, the load balance of the system is improved and average response time of the system is decreased.
