Improved Internet congestion control design based on Smith predictor

With the rapid development of computer networks, a variety of network applications continue to emerge, resulting in a surge of network data traffic. Therefore, the network congestion becomes more serious. Congestion control is facing many problems, including latency, fairness, stability and so on, especially the instability of the network caused by transmission delay. We introduce the traditional control theory into the network congestion control, and point out that the traditional PID control can not be applied in the congestion control. Finally the P+SP control method with better effects is proposed, and the corresponding improvement measures are put forward for the phenomenon of no self balancing.
