Performance Evaluation of Transmission Algorithms for CSMA/ID WDM Ring Networks

As data traffic increase rapidly, IP over WDM (Wavelength Division Multiplexing) transport will replace conventional SONET transport in current metropolitan area networks. Such networks will require new MAC protocols to efficiently share network bandwidth among multiple network nodes. This research project describes and evaluates a novel Carrier Sense Multiple Access with Idle Detection (CSMA/ID) MAC protocols for IP over WDM ring networks. The paper focuses on the influence of performance for the packet scheduling algorithms included FIFO, OPF_CA and OPF_CF. An analytical model is developed to evaluate the performance of the protocol, with simulation results showing good network efficiency and will be an excellent candidate for next-generation metro networks.
