The future computer network will be a high-speed packet-switched network that offers a wide range of services, supports a wide range of application needs, and has integrated service support capabilities.To fully improve the performance of such networks, it is crucial to design an efficient flow control mechanism This paper proposes an explicit rate (ER) control mechanism based on fuzzy logic, based on the related research in ATM network.Through the management of the switch buffer instantaneous queue length and its rate of change, and using a group Language rules, which calculate the switch can support the traffic rate.The simulation results show that the mechanism is stable and robust; it can effectively avoid network congestion and have a higher link bandwidth utilization
