Due to the serious effectiveness of congestion problem in the Internet performance, congestion control has the most concern in the network community. Several End-to-End mechanisms were developed to overcome this problem. However, most of the existing mechanisms adapt the sending rate at the sender, when detecting congestion, without considering the network status. This behavior degrades the Internet performance. This paper presents a new fuzzy controller to adjust the sending rate at the sender dynamically based on the network load. The intended controller is employed to enhance the TCP-Vegas and the performance is evaluated by using the well-known Network Simulator NS-2. The results indicate that the intended controller the AT&T real network increases the throughput and decreases both the packet loss and packet delay.
