Efficient QoS Support in a Slotted Packet-Switched WDM Metro Ring

摘要

This paper proposes a collision-free access protocol based on scalable slotted ring network architecture. Multiple QoS classes are supported directly in optical layer. The QoS scheme adopts the fixed home slots strategies to satisfy the requirements of services. Furthermore, efficient slot reuse is proposed. Simulation results show that the protocol can achieve good performance to guarantee the quality of traffic.
