The author thinks that congestion control of computer networks has much inherent property of distributed control system. Intuitively, the framework of explicit rate-based flow control defined in TM4.0 is modeled as the first order system with delay. Regarding the queue length as control object, the regulative system is devised applying with fuzzy control theory. The algorithm fairly and effectively allocates the available bandwidth among all active ABR virtual connection. The results and analysis of simulation show that this proposed novel algorithm has very good all-around performance.
