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.

“…There are three inputs of the algorithm in the management block, including V-BVT resources, optical network status and the Ethernet traffic on VON. V-BVT resources contains the modulator and subcarriers resource pool, including the details of modulation types, modulator baud rates, the available number of each type, required OSNR for a given modulation type in a given baud rate, available subcarriers number, and central frequency of each available subcarrier [22]. The optical network status consists of pre-calculated path candidates between given source and destination pairs, channel OSNR per link based on a given transmitted data rate, latency and available spectrum slots of each link based on flex-grid from international telecommunication union (ITU).…”

We introduce the real-time multi-technology transport layer monitoring to facilitate the coordinated virtualisation of optical and Ethernet networks supported by optical virtualiseable transceivers (V-BVT). A monitoring and network resource configuration scheme is proposed to include the hardware monitoring in both Ethernet and Optical layers. The scheme depicts the data and control interactions among multiple network layers under the software defined network (SDN) background, as well as the application that analyses the monitored data obtained from the database. We also present a re-configuration algorithm to adaptively modify the composition of virtual optical networks based on two criteria. The proposed monitoring scheme is experimentally demonstrated with OpenFlow (OF) extensions for a holistic (re-)configuration across both layers in Ethernet switches and V-BVTs.

“…The authors in [1]- [6] studied the mapping problem in optical networks, taking into consideration some optical layer constraints, such as the transmission reach constraint and the spectral continuity/conflict constraints. Some results experiments can be seen in [16] and [17]. The authors in [18] study the problem of survivable VON mapping in a flexible grid optical network with programmable regenerators that are capable of converting spectrum and modulation format.…”
