Comparison of Flow Forwarding Between Software-Defined and Legacy Networks Based on Fixed Routing and QoS Conditions

Abstract

The following article presents a comparison of flow forwarding between traditional and software-defined networks (SDN), focusing on the impact of routing protocols and policies. The present work evaluates the efficiency of SDN routing (bandwidth and packet loss) against the performance obtained in traditional networks and estimates the performance variation when using ad-hoc software implementations such as OpenVSwitch [1].
