The current Web service model treats all requests equivalently, both while being processed by servers and while being transmitted over the network. For some uses, such as multiple priority schemes, different levels of service are desirable. We propose application-level TCP connection management mechanisms of web server to provide two different levels of Web service, high and low service by setting different timeout for inactive TCP connection. We evaluated the performance of the mechanism under heavy and light loading conditions on Web server. Our experiments show that, though heavy traffic saturates the network, high level class performance is improved by at most 25-28%. Therefore this mechanism can effectively provide QoS services even in the absence of operating system and network support.
