摘要/Abstract

摘要： 针对目前通用的Web服务器上未实现有效的QoS控制的现状以及Web QoS控制灵活性不够、通用性不强、可扩展性不好等缺点，提出了一种基于请求目标分类的Web QoS动态控制模型，采用以控制响应时间为中心的动态控制策略，对HTTP请求进行基于目标分类的动态接纳控制以及动态的重配置处理。实验结果表明，该方法可以显著减少系统响应时间，并保证在高负载下的吞吐量的平稳性。

Abstract: In view of the lack of effective control of current Web server on QoS，and such QoS are of not flexible，not versatile and not scalable enough，a Web QoS dynamic control model based on classification of request targets is proposed.It uses a dynamic control strategy which aims at decreasing response time by conducting admission control and reconfiguring to HTTP requests which classified by request targets.The results of experiments show that our methods obviously decrease the user’s response time and ensures the stability of system throughput under high load condition.
