Synopsis:   

Internet have experienced an explosive growth accompanied with sever congestion problems. TCP congestion control mechanism is crucial for efficient use of the Internet despite largely unpredictable user access patterns and despite resource bottlenecks and limitations. This paper reviews and evaluates the current Reno and Vegas TCP congestion control mechanisms. Generally, the mechanism repeatedly increase load in an effort to find the flow rate that digests the different demands of the end devices, however, each attain different utilization of Internet resource.  Further, the authors present a new controller based on fuzzy concept to overcome the limitations of the current Reno TCP protocol. The fuzzy control in this work is a static algorithm with static rule. All the evaluation data are gained from NS2 simulator.
