The Analysis And Application Study Of Web Quality Of Service

With the development of the computer network and multimedia technologies, the Web application and HTTP requests on the Internet is increasing explosively. Many web sites had to face the problem of the server overloading.Quality of Service of web 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 filed. 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 bottleneck of the QoS control. Therefore, how to apply the web server QoS control and provide the customers the satisfied service has become the imminence problems that must be settled.Due to the above problems, in this article we do some key researches in the field. The contents of the article are as following:1. We study the main stream technique and the architecture of Web QoS system, analyze their kernel techniques. This work helps us master the latest developing trend of this field.2. We study the techniques related with Web QoS, analyze the idea they realized, especially the influence on Quality of Service of web. This work provide us theoretical bases for next work.3.We analyze the key technical factors that based on QoS security should be resolved and summarize the existing solutions.4. We bring forward a new prepositive server plan on web server and put the plan into practical effect. The validity of the prepositive server is proved by later testings.
