Paper Abstract

The paper illustrates novel proposals for medium access control protocols in all-optical communication networks based on WDM multichannel ring architectures providing one slotted channel for each destination node. In such networks, nodes are equipped with one fixed- wavelength receiver and one tunable transmitter. Three access protocols based on local status information are described. A channel inspection capability is assumed to be available for the implementation of the access protocols. Global fairness control algorithms derived from those adopted in the Metaring metropolitan area network are also proposed. Access delays and throughputs are taken as performance indices for a simulation-based comparison of the proposed protocols, in the case of a 16-node multiring with either balanced or unbalanced traffic. Simulation results show that the throughput limitations and the fairness problems induced by the network architecture can be overcome with relatively simple access protocols.
