Software-Defined Networking: Open-Source Alternatives for Small to Medium Sized Enterprises

SDN Networking is a new and emerging technology and is receiving significant considerations within organizations. Previous research predominantly emphases on SDN deployment with large Local Area Networks (LAN’s) and its use in corporate Wider Area Networks. SDN adoption within small networks is an area of research that has not been explored in any detail. This paper aims to analyze a market-leading SDN solution – Cisco DNA Centre- and identify key technologies for utilization with SME-based networks. Furthermore, this research aims to provide open-source SDN solutions suitable for Small to Medium-sized networks and show how those identified technologies could be developed and deployed within Open-source solutions. This research shows that Open-source SDN controllers are a viable and deployable solution within small to medium-sized business networks.
