Abstract

This study is intended to be a comparative study of the energy efficiency of the traditional network topology and the software-defined networking (SDN) topology. Energy efficiency has been a priority aspect in network design due to environmental concerns and cost optimization of operational costs. Traditional networking is based on the existing configuration of the hardware devices and decentralized control, which in turn results in ineffective usage of the resources. However, in contrast, SDN centralizes network control and thus facilitates energy-efficient resource allocation and optimization. In this comparison, the energy consumption profiles, the utilization patterns of the resources, and the operating strategies of both methods are evaluated. The goal of this study is to present information on SDN energy efficiency over the conventional networking method and to demonstrate how SDN can offer benefits to the environment and economy by using SDN technologies in network infrastructures. However, the selection of the specific network infrastructure may vary depending on specific user requirements.
