Research on network congestion control system based on continuous time model

Abstract

The congestion control system, as one of the key parts for the normal operation of computer network, has become a hot research in both domestic and abroad at currently. The preliminary research on congestion control system of computer network was focused on the improvement of algorithm and some researches on network behavior. This paper, based on some relative literatures, carried out a comparatively intensive research on the aspect of network congestion control and built up a continuous time model for TCP congestion control system. TCP congestion control algorithm and RED queue management algorithm, as the two parts of TCP congestion control system, are modeled independently and then cascaded into a unity. Finally, it analyzed the model stability near the stationary points, and pointed out that the stability of TCP congestion control system mainly depended on the RED algorithm. © 2012 Springer Science+Business Media B.V.
