document: Connection management for QoS service on the Web 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 for Web servers to provide two different levels of Web service , high and low service , by setting different time-outs for inactive TCP connections . We evaluated the performance of the mechanism under heavy and light loading conditions on the Web server . Our experiments show that , though heavy traffic saturates the network , high level class performance is improved by as much as 25-28 % . Therefore , this mechanism can effectively provide QoS guaranteed services even in the absence of operating system and network supports
