“…• Adding the status information at the header of the data frame [2,[14][15][16][17][18] or • Adding a separate Control Channel CC which holds the information of the slot status and of both source and destination information [19,11,[20][21][22] The separate Control Channel (CC) wavelength method is used because it enables nodes to exchange control information at high line rates and eases the implementation of enhanced access protocols with fairness control and QoS support [1] . The approval of standard IEEE 802.17 Resilient Packet Ring (RPR) serves as a testimony of the penetration of optical singlechannel ring networks into high-performance packetswitched optical single-channel MANs [1] .…”

Problem statement:The lack of uniformity in the choice of simulation platforms for optical WDM networks stands behind the difficulty of developing a common simulation environment. Correlating WDM unidirectional slotted ring network to Discrete Event Simulation (DES) encompassing event definition, time advancing mechanism and scheduler has yet to be developed. Approach: The study focused on the proposed and the development of an event based discrete simulator for the WDM unidirectional slotted ring network to facilitate the reuse of the protocol modules under a common simulation environment. The proposed network architecture implemented for the developed simulator employs a separate wavelength as the control information channel. This control information enabled the nodes to monitor their access to the transmission media. Each node was equipped with a tunable transmitter and fixed receiver for data communication. Access nodes were equipped with a fixed transmitter and fixed receiver for the control information exchange. The developed simulator had derived the use of dividing the wavelength into slots. Nodes used these slots to transmit fixed size packets. Slots can be reused by the access node after receiving packets by the deployment of the spatial reuse scheme, thus enhancing the bandwidth utilization. The developed simulator had derived the set of the parameters, events, performance metrics and other unique WDM simulator elements according to a detailed analysis of the base model. Results: The network delay and packet loss were investigated and compared to a benchmark of the modeled domain. Successful deployment of the developed simulator was proven by the generated results. Conclusion: Extensive performance analysis of WDM unidirectional slotted ring network can be deployed using the developed simulator with low computational overheads. Further enhancements were to extend the developed simulator for bidirectional slotted ring supporting fairness control and considering both uniform and non-uniform traffic.

“…Much attention has been given to the burst contention problem especially in OBS ring networks using the out-band signaling scheme for BCP. The authors in [3] solved the contention issue in WDM ring networks by adopting a token-passing scheme, but the end-to-end (E2E) delay was highly redundant. Recently, the beforehand resource reservation (BRR) using the time division multiplexing (TDM) scheme has been proposed [4], but it still has an issue regarding poor link utilization.…”

This paper presents a novel collision-less optical burst transmission scheme, namely, look-ahead optical burst transmission (LAOBT) for WDM ring networks. In the LAOBT, bursts are generated and inserted into burst streams by utilizing the void intervals of incoming bursts (IBs) in advance. The void size is estimated by splitting optical power into two paths, delaying one of the signals at the fiber delay line (FDL) and calculating IBs' residual time from the splitter to the optical cross-connect (OXC). The performance evaluation results show that our proposed scheme increases link utilization without significant increment of end-to-end delay and signaling overhead.

“…There is not much work clone in the field of OBS over metropolitanarea rings. Xu et al [6] investigated access protocols for OBS rings based on the Just Enough Time (JET) scheme and a new scheme called the Only Destination Delay (ODD). Jong [4] proposed several access protocols for multicasting in such an environment.…”
