Software defined networking (SDN) cuts the control plane of individual devices out of the picture and lets an all-knowing program called a network controller dictate how both physical and virtual network components move traffic through the network. SDN requires components with data planes designed to take instructions from the network controller instead of their own control plane. While it's important enough that SDN allows for a master controller, the really revolutionary idea behind SDN is that the network controller is programmable: we can write code that controls how the entire network will behave.
