WTFC to TCP Flow Control Proxy

Integration of different kinds of traffic on the Internet can be resolved by employing QoS policies on access networks. One possible solution is to use WTFC flow control algorithm on general access network. In this paper the WTFCTCP flow control proxy is introduced in order to exploit the ability of WTFC to estimate the optimal working point for the available capacity and to keep on average empty node buffers. A basic proxy model is defined and elementary algorithms for congestion signaling for flows directed towards access network as well as towards general Internet are applied. Simulation experiments have shown potential successfulness of the concept.
