Résumé: TCP Vegas is a congestion avoidance scheme designed to prevent the periodic packet loss which occurs in traditional schemes. Since Vegas successfully avoids such packet loss, it achieves much higher throughput than TCP Reno. However, it does not concern the fairness among source-destination pairs with different round-trip times (RTT's). In this letter, we propose a different mechanism to adjust the window size, this allows TCP to provide much better fairness regardless the large variation of RTT's.
