Summary:This paper describes a SDN-based solution that, by leveraging and coordinating many functionalities that reside at both WDM and Ethernet layers, orchestrates network resources with the aim to maximize host-to-host data transfer rate. A critical software module of this SDN solution is its quality of transmission estimator (QoT-E) based on the Gaussian Noise model. The QoT-E module allows the SDN orchestrator to predict the path feasibility before provisioning a given lightpath in the network. It can also be used to predict the optimum transmitted power and the maximum capacity which can be allocated on the lightpath. With the QoT-E provided information the SDN orchestrator can more rapidly and more efficiently reserve transmission resources at the optical physical layer.
