Software Defined Networking (SDN)

Over the past two decades, networking has been severely limited: it simply could not keep up with new demands from businesses in an increasingly digital world. However, that is all about to change thanks to the creation of software-defined networking, or SDN. Part of an ongoing wave of “virtualisation” in the IT industry, SDN allows people (particularly businesses with large IT systems) to control network behaviour through a handy piece of software, instead of having to go into the network infrastructure and alter things manually.
