Recursive Optimal Network Flow Control Algorithm Based on Predictor

With regard to the impact of multimedia digital service transfer delay in computer network, we apply the simplified Smith predictor algorithm combined with the recursive algorithm, and propose a recursive optimization control algorithm based on predictor. The method is easy to implement and has a practical application in multimedia networks. The simulation result shows that this method can adjust the service send rate and queue in buffer rapidly and effectively, can improve the link utilization, and the delay effect is effectively overcome.
