Optimal Congestion Control for High Speed ATM Networks

摘要

For high speed ATM networks, long propagation delays are very challenging for designing a stable closed loop congestion control algorithm. In [1], the famous Smith's principle is used to design a feedback control law for congestion avoidance in high speed ATM networks. In our work to be presented here, it is shown that significant improvement could be made to enhance the system utilization by optimization approach. Comparison is made on an illustrative example by using these two approaches.
