“…bandwidth variable cross-connects or spectrum selective switches) as well as flexible control plane, are also considered essential tools. A flexible optical networking paradigm has been proposed to provide all these features and the interested reader interested can refer to [15], [20], [21] for more details. In this manuscript, we focus on flexible transceivers and the network operation aspects directly dependent/related to them.…”

“…Authors in [24] identify several transponder parameters that can be controlled, such as the line rate, modulation format, code, central frequency of the optical flows, and the association of optical transport network (OTN) streams with a specific optical flow. A review of several studies, related to the software defined optical networks (SDON), can be found in [21]. Majority of researchers use the OpenFlow protocol, in order to control and configure the physical devices.…”

Abstract-Elastic optical networks (EON) have been proposed to meet the network capacity and dynamicity challenges. Hardware and software resource optimization and re-configurability are key enablers for EONs. Recently, innovative multi-carrier transmission techniques have been extensively investigated to realize high capacity (Tb/s) flexible transceivers. In addition to standard telecommunication lasers, optical carrier generators based on optical frequency combs (OFC) have also been considered with expectations of reduced cost and inventory, improved spectral efficiency and flexibility. A wide range of OFC generation techniques have been proposed in the literature over the past few years. It is imperative to summarize the state of the art, compare and assess these diverse techniques from a practical perspective. In this survey, we identify salient features of optical multicarrier generators, review and compare these techniques both from a physical and network layer perspective. OFC demultiplexing/filtering techniques have also been reviewed. In addition to transmission performance, the impact of such sources on the network performance and real-world deployment strategies with reference to cost, power consumption, and level of flexibility have also been discussed. Field trials, integrated solutions, flexibility demonstrations are also reported. Finally, open issues and possible future directions that can lead to real network deployment are highlighted.

Traditionally, mobile ad hoc networks (MANET) and hybrid optical-wireless networks, also known as fiber-wireless (FiWi), have been considered disjointly and independently, with no synergic management solutions. The former has primarily focused on dispatching packets among mobile nodes in infrastructure-less and very dynamic environments, the latter on offering high-bandwidth and low-latency access to cellular-equipped mobile nodes. The recent advancements and penetration of software-defined networking (SDN) techniques have stimulated the adoption of SDN-based flexible monitoring and control also for the MANET and FiWi domains. In this perspective, the paper originally proposes a model and an architecture that loosely federate MANET and FiWi domains based on the interaction of MANET and FiWi controllers: the primary idea is that our MANET and FiWi federated controllers can seldom exchange monitoring data and control hints the one with the other, thus mutually enhancing their capability of packet management over hybrid FiWi-MANET networks. Our model is applied to several relevant use cases to practically point out the benefits of the proposal in terms of both load balancing and fairness improvements.

“…In [9], the authors propose a virtual topology design and lightpath routing algorithm based on the concept of loose virtual topologies, it pluses lightpaths generated by MaxSingleHop [4] algorithm for unsatisfied traffic in the ring. In [6], the authors split the virtual topology problems into several subproblems: virtual topology design, routing for lightpaths, wavelength assignment. Although these papers focus right on the IP over WDM traffic engineering problems, but all of their algorithms are based on heuristic approaches and can't be analyzed mathematically.…”

Abstract. As the development of optical communication technologies such as Wavelength-Division Multiplexing (WDM), it is important to support virtual private networks (VPN) over WDM networks. In order to overcome the limits of WDM network capacity and achieving more revenue new VPNs, an optimal model supporting both optical VPN and IP VPN on WDM networks is proposed to admit the maximum number of new VPNs without influencing the QoS guarantee for the existing VPNs. Furthermore, three heuristic algorithms are designed to simplify the computation process of getting optimal solution. The simulation results over MESH WDM networks show the algorithm can takes advantage of the reliable transmission capability of WDM networks and provides diverse QoS for different traffic streams by different quality of optical transmission.
