Both fair access and high aggregate network throughput can be achieved with a low complexity distributed access protocol by properly handling node access through all WDM channels.  ...  The paper deals with fairness issues in a slotted, single-hop, WDM (Wavelength Division Multiplexing) optical architecture, based on a folded bus topology, previously proposed as a broadband access system  ...  The model considers a uniform overloading traffic scenario on all channels, as the Multi-MetaRing protocol regulates node access only when the network is highly loaded.  ...
