Computationally efficient congestion controller for data transmission networks with variable packet loss

In our paper we consider the issue of controlling the flow of data in connection-oriented communication networks with multiple data sources and variable bit rate. Effective control of such a system is not a trivial task since all sources are characterized by individual delays and unpredictable packet loss rates. In this work a sliding mode control scheme is proposed for data congestion control in the considered networks. The controller uses a particular delay-free model of the network and a sliding hypersurface defined in the extended state space. It is demonstrated that the proposed scheme ensures all essential properties of the network while offering high computational efficiency.
