Software Defined Networking (SDN) is an architecture—first defined circa 1995—that physically separates the network control plane (decisions about traffic flows) from the forwarding plane (moving chunks of data between points A and B). Practically this simply means controlling network hardware devices (think routers, switches, Wi-Fi access points) by using software that is physically hosted elsewhere (think an orchestrator or controller platform). A SDN architecture provides numerous advantages: it abstracts (and simplifies) the entire…
