The increase in need for a high capacity internet has become the driving force behind recent developments in optical transmission and networking technologies. It is believed that the growth of the internet will one day be constrained by its power consumption values. Optical networks have the capacity to accomodate the exponential traffic growth in the internet with low capital expenditure cost. In order to lower the operational expenditure cost of optical networks, power consumption of various equipment need to be kept at a bare minimum. The main objective of our work is to analyze the energy consumption of optical backbone networks and identify novel techniques to minimize the consumption. The study also aims to develop frameworks and algorithms to increase energy efficiency of optical backbone networks. In order to fullfills these objectives, technologies and concepts related to three different engineering approaches have been identified and used in this work. In this seminar, the progress of the research is presented with some obtained results and anticipated future works.

About the Speaker
