Congestion control provides quality of service over the best effort networks. Congestion occurred when arrival rate to a router is greater than its departure rate. In this paper, using fuzzy logic approach, we have proposed a modified TCP equation-based active queue management mechanism which is based on traditional GREEN algorithm. Here we present our fuzzy GREEN controller which is expected to act as a congestion controller in the routers. We have simulated our fuzzy method both with and without background Pareto traffic and the results show the superiority of our fuzzy method compared to the non-fuzzy one in both long-lived as well as short-lived connections
