This paper presents a refined model for the fuzzy logic implementation of an available bit rate (ABR) flow control switch. This refined model is named fuzzy explicit rate (FUER) switch mechanism. FUER switch mechanism is designed to effectively perform congestion control on ABR traffic in asynchronous transfer mode (ATM) networks. The performance of FUER scheme is evaluated against those of two other explicit rate (ER)-based switch mechanisms using simulation in particular local area network (LAN) and wide area network (WAN) environments. On the whole, FUER scheme performs better than the other schemes. Although it has the smallest control parameter set, it is a more efficient and scalable ER-based switch mechanism.
