Abstract

Traditional TCP variants use packet loss as the indicator of congestion and reduce the congestion windows size, which results in degradation of TCP throughput. Subsequently, ECN is widely used to send the congestion feedback to end hosts by couple with AQM on routers. Based on the TCP fluid model under ECN mechanism, an enhancement over wired/wireless hybrid networks, WECN, is analyzed. The contribution of this paper is to implement WECN in Linux and combine it with TCP Reno, TCP Westwood in testbed. The results show that WECN can be extended to current TCP variants and can improve TCP throughput in lossy links.
