Software Defined Networking: What it Means for Your Business


SDN is Software Defined Networking; promising a faster response, improved user experience with business applications, and reduced costs. It’s the technology of the moment and you may have already come across this term. But what exactly is SDN and what can it do for your business?

Software Defined Networking is essentially a product of virtualisation. SDN technology creates a new layer of ‘middleware’, one which allows network administrators to make network device changes using a software interface. This means we no longer have to manually configure hardware and physically access network devices. The benefits? Small businesses can save both time and money and focus their resources on the most important tasks at hand.

SDN Architecture: The Basics

This basic diagram from Open Networking Foundation shows us the basics of the three key layers to SDN; the application layer, the control layer, and the infrastructure layer. The SDN controller removes the control plain from the network hardware to facilitate automated network management – it is centrally managed making it easy to update applications to meet the changes of the modern and dynamic business.

To keep up with the complexity of such a process, networks need to be able to adapt. Although some business owners don’t think it’s possible to have the speed and agility required, experts such as believe that SDN is the answer, with improved service uptime to boot.
