Abstract

Internet grows rapidly to serve high performance accordingly the technologies of semiconductor, optical communication, and Next Generation Internet evolves. Therefore, the study to enhance TCP efficiencies for high performance becomes very important. The conventional TCP has structural problems of limiting the capability of maximum throughput and the bandwidth probe by their physical buffer size of receive window. This paper introduces "Virtual Window" at receiving hosts to relieve these problems. The Virtual Window represents the throughput of receiving host in processing receiving packets during inter-arrival times of segments when sending host sends TCP segments with regular time intervals within RTT. Consequently, with the proposed algorithm, the better TCP performance for very high speed Internet can be guaranteed if higher performance host is used, with which the bigger size of Virtual Windows is allowed. The proposed algorithm's simulation results using Network Simulator 2 verifies that the throughput of TCP is improved by 1.5 ~ 5 times than that of conventional TCP algorithm.
