Abstract
Several works have been done in order to balance the energy consumption of the network with traffic which aims to have a positive impact on the CO2 emission. However, CO2 and energy consumption cannot be considered proportionate if the means of electricity production differs. In this paper, we have proposed two different metrics namely Carbon Emission Factor and Non-Renewable Energy usage percentage for achieving green network. We have designed an algorithm considering these metrics as objective functions. We have considered a software defined network approach and provided a set of data and control plane for each metric. Their performances are then analyzed and compared with respect to green policy enabled Shortest Path First algorithm. All the experiments are conducted on GÉANT network with realistic demand size. A comprehensive analysis of the quality of service parameters like the end to end delay and packet loss is also done for each metric of the algorithm.
