SDN-Based Load Balancing to Achieve Energy Efficiency in Enterprise Networks

EasyChair Preprint 15288

Abstract

Software Defined Network (SDN) is taking over traditional networks for better performance, resource management, and lower network operating costs. In this paper, we discuss load balancing and energy awareness in SDN. We explore how these features correlate and minimize energy consumption and traffic congestion through traffic engineering. We use a round-robin load balancing technique and observe round trip time (RTT). TCP and UPD traffic flows are analyzed using parameters: transfer, bitrate, jitter, and packet loss. For energy consumption, we measure CPU utilization before and after load balancing. Results highlight that load balancing reduces RTT by up to 44.88%. Even distribution of load reduces CPU idle time to less than 90% and improves utilization. Furthermore, load balancing reduces jitter by 46% while maintaining bitrate.

Keyphrases: Controller policies, Load Balancing, Round Robin, SDN Control Plane, Software Defined Network, average rtt, energy awareness
