Reduction of Energy Consumption based on Replacement of Routers with SDN Switches

Abstract

Software Defined Networking (SDN) is a promising solution because of many advantages over the traditional network. Due to these advantages, SDN can be considered as a tool for energy efficiency in ICT (Information and Communication Technology) networks. In this paper, we have made a comparison between energy consumption in real IP/MPLS (Internet Protocol/Multi-Protocol Label Switching) network and designed SDN network. The results show that a significant reduction of energy consumption is achieved for a scenario with designed SDN solution.
