Research In Model Of Web QoS Control Through Self-Tuning

With the development of the computer network and multimedia technologies, the Web application on the Internet is increasing explosively. Most of the Web applications are the HTTP requests. Many web sites had to face the problem of the server overloading. The main symptom is that users have to wait a very long time for the HTTP response and even the HTTP requests will be rejected.The responding time is generally influenced by two elements: the quantity of the service of network's transfer layer and the performance of the web server. Recently years, the research has been carried out actively in this field. In condition of the server overloading, if any measure was not taken about the QoS control in the applications layer,although the QoS of the network transferring is ensured very well, the request may also be rejected or the responding time be delayed so long that leads to "reject request" result. So we could conclude that the overload of the web server is becoming the botleneck of the QoS control. Therefore, how to apply the web server QoS control and provide the customers the satisfied services, has become the imminence problems that must be setled.In this paper, we do some research of Web QoS control deeply, the strategy of classified service provide the diffeniated customers the diffeniated services.On the one hand, we propose prototypes of...
