This article considers a WDM slotted‐ring network architecture. A slotted MAC protocol was designed to be used in a metropolitan environment. The results of a discrete event simulation are presented. Assuming that a maximum load threshold is not exceeded, fairness between access nodes is achieved by introducing a very simple mechanism. Excellent queuing delay and packet dropping probability results are obtained. Future developments are presented as they are expected to improve the efficiency and introduce QoS capabilities and congestion avoidance mechanisms. Copyright © 2001 John Wiley & Sons, Ltd.
