An Improved Congestion Control Scheme for High-Speed Computer Communication Networks by Using Smith's Principle
Tan Lian, PR China · 2003
In this paper, classical control theory and Smith's principle are applied in designing a class of effective and simple congestion control schemes for high-speed computer communication networks. Mathematical analyses and simulations verify the efficiency of the congestion control schemes. The proposed congestion control laws guarantee full utilization of network links and stability of network queues so that the network has no data loss in a general network topology and traffic scenario. The approach has some advantage over the usual Smith's principle based congestion control scheme; it can be applied to those networks that may have smaller bottleneck capacity. Theoretical analyses and simulation results show good performance of networks if implemented by the congestion controllers, which are designed on the basis of the improved Smith principle.
