Abstract :
This paper first introduces existing congestion control algorithms and analyses their weakness. And after discusses the features and requirements of network topology simulation system, a congestion control scheme based on improved RED algorithm named DFCC was presented. DFCC reduces the package loss by adjusting link delay dynamically when congestion happens. And by means of twice optimization of adjusting rate of the link delay, it can ensure the stability of the average length of the queue. The experiment results indicate that when the amount of packets increases gradually, the package loss of DFCC scheme will distinctly less than RED algorithm.
