In this paper optical transport networks (OTN) and different control planes approaches are presented. For the Software Defined Networks (SDN) configurations and mode of operations such as implicit and explicit are discussed. The path latencies of two control plane approaches are examined and numerical results are presented on the path metric. The results are derived from a simple network simulation...
Super-channel (or multi-carrier) transmission is today one of the most promising techniques for the support of high line rates, which are required to satisfy the massive increase of Internet traffic. Moreover, flex-grid optical networks seem to be the candidates for backbone networks by enabling high spectral efficiency thanks to the adoption of the ITUT flex-grid. Such networks may suffer from spectrum...
