The main objective of this paper is to demonstrate how simple fluid-flow model of TCP (Transport Control Protocol) behavior allows to exploit robust control methods earlier developed for nonlinear time delayed feedback systems. Test setup consists of “far” and “near”, in terms of transport delay, groups of TCP flows and AQM (Active Queue Management) router. It was proposed to control “near” flows for “far” long-lived flows stabilization in uncertain network parameters environment. The comparison of RED (Random Early Detect) queue controller and robust controller simulation and experimental results are presented.
