Paper 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.
