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.

Abstract-In this paper we examine the relationship between the effective capacity (stability limit) of unidirectional and bidirectional packet-switched wavelength division multiplexing (WDM) ring networks for multicast traffic. We consider both bidirectional rings with one packet copy transmission per wavelength channel and two packet copy transmissions. We first prove bounds for the ratio of the multicast capacity of the bidirectional ring to the multicast capacity of the unidirectional ring. Specifically, we show that this ratio is at least two for two copy transmission in the bidirectional ring, and at most two for one copy transmission. We derive closed form expressions of the multicast capacity ratios for networks with a large number of nodes and from these expressions show that the ratios tend to two for a large number of multicast destinations. We demonstrate that for the bidirectional ring with two copy transmission the ratio becomes as large as 2.276. We also find that in the bidirectional ring, the capacity gain with two copy transmission over one copy transmission reaches 30.4%.

“…The methods in [2] approximately achieved the same blocking probability independently of the location of the source and destination nodes. In [3], the fairness between unicasting and multicasting was considered in a ring metro WDM network. The study in [4] focused on fairness between dependable and non-dependable connections.…”

Hop constraint based admission and fairness control in IP-over-WDM networks

From both user and operator perspectives, fairness is an important aspect in IP-over-WDM networks where Label Switched Paths (LSPs) are dynamically groomed over optical networks. The setup of LSPs with long distances experiences a higher blocking probability due to both lightpath establishment unfairness in the optical layer and link cascading effect in the IP/MPLS layer. A simple LSP connection admission and fairness control mechanism is proposed in this article. This control mechanism is based on hop constraint, in which an LSP is accepted with a pre-assigned probability according to its distance and the hops of its route. Through suppressing connection of short-distance LSPs that overuse bandwidth to facilitate the setup of LSPs with long distances, this proposal achieves fine distance fairness performance with a slight overall blocking probability increment.
