In this paper, a new robust congestion control strategy is proposed for a multi-services architecture, namely a Differentiated-Services (DiffServ) network. In virtue of their robustness capabilities, Sliding Mode-based Variable Structure Control (SM-VSC) techniques are utilized to design our proposed controller on the basis of an inaccurate/uncertain Fluid Flow Model (FFM). Developed for an interconnected network as a hop-by-hop distributed control scheme, the proposed algorithm is shown to achieve the desired performance specifications and requirements. Moreover, the error dynamics of the overall time delay dependent network is analytically shown to be L2 stable.
