This is done by decoupling the system that makes decisions about where traffic is sent (the control plane) from the underlying systems, that forward traffic to the selected destination (the data plane). SDN requires some method for the control plane to communicate with the data plane. One such mechanism, OpenFlow, is often misunderstood to be equivalent to SDN, but other mechanisms could also fit into the same concept….
