This paper proposes a slotted access protocol for WDM ring network architecture suitable for Metropolitan Area Networks. Each node uses a pair of tunable transmitter and tunable receiver to communicate exploiting all the fiber data wavelengths. Also, each node uses a pair of fixed tuned transmitter and fixed tuned receiver to exchange control information over a separate control wavelength. The proposed protocol efficiently faces the serious scalability problems that many WDMA ring protocols introduce, due to the use of a dedicated data wavelength per node for either transmission or reception. Performance evaluation is provided through theoretical analysis and through a discrete event simulation model using both Poisson and self-similar traffic sources, giving more realistic performance evaluation. Simulation results show that the proposed WDMA protocol manages efficient network utilization providing excellent fairness among the nodes. Comparative simulation results prove that the proposed access scheme achieves significant performance improvement compared with the study of [5] which employs nodes with one fixed tuned transmitter.
