In wired and wireless mixed networks, split-connection type proxies have been proposed to improve TCP (Transmission Control Protocol) throughput. A proxy is placed at the boundary between a wired network and a wireless one and splits a TCP connection which is established between a host in one of these networks and a host in the other networks into two virtual TCP connections. In this paper, under such environment that IEEE 802.11 WLANs are used as wireless networks, we first investigate throughputs of TCP connections with a proxy and show that although throughputs of downflows (flows from hosts in a wired network to a host in a WLAN) are improved, throughputs of upflows (the reverse of downflows) become smaller compared to those of TCP connections without the proxy. And we clarify that such throughput degradation is caused by congestion of a WLAN, and we propose a method to suppress such congestion.
