Abstract
In this paper we propose a discrete time sliding mode congestion controller for a single virtual circuit in connection-oriented communication networks. The circuit is characterized by the non-negligible propagation delay, the maximum link capacity and unknown, time-varying data loss rate. The proposed controller generates non-negative and limited transmission rates, ensures upper bounded queue length in the bottleneck link buffer and may guarantee full utilization of the link capacity. In order to ensure fast reaction to the unpredictable data loss and unknown changes of the available bandwidth, the controller employs the dead-beat sliding hyperplane. However, straightforward application of the dead-beat paradigm could lead to unacceptably big transmission rates. Therefore, the controller is designed using the concept of the reaching law, which helps to attenuate the excessive magnitude of control signal at the beginning of the transmission process.
