Abstract

Several studies have considered control theory tools for traffic control in communication networks, as for example the congestion control issue in IP (Internet Protocol) routers. In this paper, we have two main goals: the first one is to obtain a controller which approximates the true system containing a delay; this will be ended by choosing the adequate degree of Padé approximation. Our second goal is to attain a robust AQM (Active Queue Management) controller coping with uncertainties on the network parameters and this, by using Kharitonov approach.
