Energy Consumption Reduction of the Spectrally-Spatially Flexible Optical Networks Based on the Energy Savings Algorithm

Abstract

Energy reduction and conservation is gaining interest in our society rapidly in the last decade. 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). We then evaluate our approach using existing, real-life networks in the simulation testbed. Two primary metrics of the evaluation are energy usage, which directly relates to the operational cost of the networks, as well as bandwidth blocking probability, which affects how many customers network operators can serve. Our algorithm achieves similar efficiency for routing as the ones in the literature with the average double reduction of the energy consumption.
