“…Another important avenue is to examine the impact of the DBA design dimensions on delay variations and to explore mechanisms that jointly reduce mean delay as well as delay variations [39]- [41]. Moreover, the internetworking of EPON access networks, which were considered in this study in isolation, with metro networks, e.g., [42]- [45], poses several open research challenges for efficient interoperability and bandwidth management [46]- [48].…”

Abstract-The implications of the main components of dynamic bandwidth allocation (DBA) algorithms in ethernet passive optical networks, namely grant scheduling framework, grant sizing, and grant scheduling, have to date been examined in isolation. In contrast, we conduct a comprehensive throughput-delay comparison study of the three main DBA components; whereby, for each of the DBA components, we consider a range of common mechanisms. Our comparison study considers a number of novel combinations of mechanisms for the individual DBA algorithms, such as the double-phase polling (DPP) scheduling framework combined with limited with excess distribution grant sizing, and shortest propagation delay (SPD) first scheduling. We find that this (DPP, Limited with excess, SPD) combination in conjunction with a novel excess sharing mechanism outperforms previously studied DBA algorithms.

“…• 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.

“…Transmitted packets travel towards the folding point in a first ring traversal, are switched to the reception path, and then received during a second ring traversal. If each node can become the folding point (i.e., if each node has a switching capability), then the network preserves the interesting restoration property of rings, as described in [13]. Although this architecture does not exploit wavelength spatial reuse, it avoids transmission impairment (e.g., noise recirculation) typical of ring topologies, while guaranteeing that all the network traffic accepted prior to the fault can be supported also after restoration (note that this may not be the case in ring networks with spatial reuse).…”

Abstract-Single-hop wavelength division multiplexing (WDM) optical ring networks operating in packet mode are one of the most promising architectures for the design of innovative metropolitan network (metro) architectures. They permit a cost-effective design, with a good combination of optical and electronic technologies, while supporting features like restoration and reconfiguration that are essential in any metro scenario. In this article, we address the tunability requirements that lead to an effective resource usage and permit reconfiguration in optical WDM metros. We introduce reconfiguration algorithms that, on the basis of traffic measurements, adapt the network configuration to traffic demands to optimize performance. Using a specific network architecture as a reference case, the paper aims at the broader goal of showing which are the advantages fostered by innovative network designs exploiting the features of optical technologies.Index Terms-All-optical networks, dynamic network configuration, logical topology design, wavelength division multiplexing (WDM) packet rings.
