XCP bandwidth compensation algorithm based on sliding mode control in time vary network

Network propagation delay and system parameters are always changing, to this case, the paper applied sliding mode control theory to set reasonable output bandwidth in dynamic network for XCP, and thus to compensate the uncertainty existing in the feedback factor. The source adjusted the sending rates according to it so that the network output could have high throughput and a smaller queue length. The algorithm has strong robustness caused by the network jitter due to the uncertainty of network model and the time change of the network parameters, as well as the time delay of the system state. Simulation results show that the algorithm can improve the bandwidth utilization effectively in dynamic networks, and compare with PII-XCP algorithm, this algorithm can adapt to the dynamic nature of the network and time delay.
