摘　　要：该文将服务器系统和通信访问网络考虑为一个整体建模,给出了一个基于HTTP的Web系统的服务性能模型,并将模型扩展到了多服务器系统;分析了各模型参数对网络服务性能的影响,提出了避免死锁状态的方法和增加服务器的速率原则;最后对比了几种提高服务性能的方法。仿真结果证实了模型的有效性。In this paper, the service performance modei for Web system based on HTTP is presented, in which the Web server and the communication network are considered as one system to construct an open Markov queue network. This model is also extended to multiple-server system. After analysing the effects of the parameters on the performance, the method to avoid deadlock and the speed rule to add new server are investigated. Finally, several schernes for improving Web server performance based on different congestion conditions are evaluated and compared. Simulation results confirmed the validity of the model.
