\r\n SDN is a networking paradigm. A networking style. Before understanding SDN, we have to understand 2 things.\n1.Data Plane: Data Path which actually forwards the packet or data from the input port to output port.\n2.Control Plane: This has the logic of how to move the packet from input port to output port. Control Plane directs the data plane.\r\n

\r\n

\r\n Pre SDN , the two planes data plane and control plane both were residing in the network devices like routers, switches, firewalls etc.\nNow with SDN, the control plane and data plane has been separated i.e, Control Plane is moved out of the network devices and has been placed onto the central server. One SDN Controller can control many Network Elements. Granularity of the separation is left to the implementation.\r\n
