Abstract

This paper describes and analyzes SR³ (Synchronous Round Robin with Reservations), a collision-free medium access control protocol for all-optical slotted packet networks based on WDM multi-channel ring topologies where nodes are equipped with one fixed-wavelength receiver and one wavelength-tunable transmitter. SR³ achieves an efficient exploitation of the available bandwidth, guarantees a throughput-fair access to each node, and allows nodes to reserve slots, thereby permitting a tight control on access delays. The latter feature makes the proposed protocol well suited to provide support to traffic classes with different QoS requirements. Simulation results show that SR³ provides very good performance to guaranteed quality traffic, bringing significant performance improvements also to best-effort traffic.
