Transmission Control Protocol (TCP) is one of the most widely used transport protocol for reliable data transfer. TCP uses window-based °ow control through acknowledgement message from a destination for packet. TCP Reno and Vegas are widely used as TCP. However, they don`t use bandwidth e±ciently in the Wide-bandwidth Networks because of its low window scalability. A solution to this problem that has been pursued by many authors is to increase the rate at which window is increased and thereby shorten the congestion duration. Early work along these lines includes the Scalable TCP and FAST TCP. Although these solutions are proved to have good window scalability, they still su??er fairness utilization problems when many °ows arrive at a single bottleneck and work with the standard TCP.
In this paper, we propose the method to improve TCP fairness in the TCP Networks and also propose the method to improve Link Utilization in the Hybrid TCP Networks. We introduce the analytic model of the proposed algorithm and prove the system based on our algorithms to be asymptotically stable. Through simulations, we show the performance improvement of the system.
