Energy Consumption Reduction of the Survivable Spectrally-Spatially Flexible Optical Networks

Energy reduction is rapidly gaining interest due to several environmental changes in our society. In this paper, we design an energy-efficient algorithm for the problem of Routing, Modulation, Core and Spectrum Assignment in Spectrally-Spatially Flexible Optical Networks (SS-FON) with the network survivability. We then evaluate it using existing, real-life networks in the CEONS simulator. Two primary metrics of the evaluation are operational expenditure (OPEX) and Bandwidth Blocking Probability (BBP). The numerical experiments confirm the efficiency of our solution compared to the ones existing in the literature.
