Design and analysis of a hybrid access control to an optical star using WDM

Abstract

The implementation of a local area network based on a passive optical star is considered. Two distributed synchronization problems are addressed: (1) generating a global event clock for synchronizing the nodes' operation, and (2) distributed scheduling for accessing the shared passive medium, which is a hybrid (deterministic and random) technique. A hybrid scheduling algorithm is presented that is fair and equivalent to a distributed queue.
