Smith's principle for congestion control in high speed ATM networks

Abstract

In high speed communication networks, long propagation delays are critical for the stability of closed loop congestion control algorithms. In this paper, Smith's principle is proposed as a key tool to design a feedback control law for congestion avoidance in high speed ATM networks. The proposed algorithm assures the stability of network queues and the full utilization of network links in a realistic scenario where many connections, with different propagation delays, share the network. Finally, Smith's principle is proposed to enhance the flow control algorithm of the TCP Internet protocol.
