With SDN,control, data and management planes are separated into 3 different layers. Data plane is made up of the physical h/w components that carry out the data forwarding ops. Control plane is centrally located and interfaces with both management plane and data plane. Management plane communicates with control plane, which in turn sends instructions to the data plane.
In a traditional network infra, these three planes are tightly integrated on the same dedicated devices. With SDN, the control and management planes are abstracted into a software layer independent of the hardware components, which provides a more agile and efficient network to better accommodate today's dynamic workloads.NFV architecture differs from both traditional and SDN architectures by virtualizing network operations and removing the dependency on proprietary hardware altogether, relying instead on COTS hardware and hypervisor technologies to deliver network services.
