Modelling slotted multi-channel ring all-optical networks

This paper presents an approximate analytical model for the evaluation of throughput and access delays in high-speed all-optical networks with slotted multi-channel ring topology, where each channel is shared in statistical time division by all nodes transmitting to one destination using a collision- and contention-free access protocol based on a channel inspection capability. Nodes are assumed to have only one queue to store packets for all destinations; two configurations are considered: the single buffer queue and the infinite buffer queue. Simulation results are used to assess the accuracy of the approximate model.
