摘要
现在的Internet服务模式已经进入以电子交易和多媒体业务为主体服务的时代,为了在Internet上提供端到端的QoS保障,服务器的工作效率以及对各种不同的HTTP请求的响应时间已成为WebQoS问题的研究核心。论文对WebQoS控制组件中分类策略以及工作进程调度策略以离散时间型轮询的方式对其进行了数学上的分析,得出系统各优先级队列的平均排队对长,以及系统中HTTP请求的平均等待时间。
The server model of the Internet at present has been in the stage of which e-trade and multimedia server are the principle part.In order to provide the end-to-end QoS assurance in the Internet,the sever efficiency and the time in response for the different HTTP requests are the main issue in the study of Web QoS.By using the theory of the discrete time polling systems,the control policy is validated in mathematic and the average length of priority classes and the average wait-time of the HTTP requires in the system are given.
