Abstract: A great deal of research has been devoted to solving the problem of network congestion posed against the context of increasing Internet traffic. However, there has been little concern regarding improvements in the performance of Internet servers such as Web/Web proxy servers in spite of the projections that the performance bottleneck will shift from networks to endhosts. In this paper, we propose a new resource management scheme for Web/Web proxy servers, which manages their resources for TCP connections, effectively and fairly. In the proposed system, we focus on the effective use of server resources by assigning dynamically the send/receive socket buffer according to the required size of each TCP connection, and terminating positively the idol persistent connection. Also, we validate the effectiveness of our proposed scheme through simulation and implementation experiments, and confirm conclusively that Web/Web proxy server throughput can be improved by 25% at maximum, and document transfer delay perceived by client hosts can be decreased by up to 90%.
