Comparison between BECN-capable TCP new-Reno and TCP Vegas

TCP is the most important transport protocol in the Internet. In this research, the backward explicit congestion notification (BECN) option is enabled for TCP New-Reno flows and then the performance of this combination is compared with that of TCP Vegas. In all the cases, the bottleneck router has random early detection (RED) capability. The comparisons are made for connections with equal and unequal round trip times (RTTs), in environments that can be homogeneous or heterogeneous. Also, two different types of traffic, FTP and Web are analyzed in the experiments
