Abstract:
Software Defined Networking (SDN) paradigm has been attracting an increasing research interest. Promising features of SDN are enabling programmable network components and separating the control plane and the forwarding plane. It promises several advantages such as flexibility without sacrificing forwarding performance, high efficiency through optimized routing, ease of implementation and administration, and cost reduction. On the other hand, energy efficiency in networking is an issue as energy cost contributes significantly to the overall costs in information and communication technologies. Thus, energy efficient mechanisms in SDN components has become indispensable. In this study, we address the importance of energy efficiency mechanisms in SDN. We propose a classification of methods for improving energy efficiency in SDN and describe each group of solutions with their principles, benefits and drawbacks. To the best of our knowledge, our study is the first one that focuses on state-of-the-art energy efficiency strategies for SDN, discusses open issues and provides guidelines for future research.
