Software-Defined Networking (SDN) SDN is a new approach to designing, building and managing networks. The basic concept is that SDN separates the network’s control (brains) and forwarding planes (muscles) to make it easier to optimise each. This will allow enterprises that deploy a SDN to shape traffic around the network, to automate the deployment of services, while making intelligent decisions about the network as a whole.

TYPICAL COMPONENTS OF A SDN This is the area where developers build the applications that add the value to the SDN (provisioning, automation, orchestration, intelligent routing, security and load balancing).
The “brains” collating information across the network, providing a centralised view of the overall network and sending commands to networks devices below (examples from NEC and Big Switch). Through the Controller, network administrators can quickly and easily make and push out decisions on how the underlying components (switches, routers) will handle the traffic.

NETWORK DEVICES:
SDN starts with the physical and virtual switches from vendors such as Avaya, Extreme Networks, Radware, etc. Despite claims to the contrary, physical network devices will still be very much a part of SDNs.
Communicating between the intelligent applications and the controller. Currently no standard API, the ONF is looking into this. Used to communicate between the controller and the network devices. Openflow is the most common example.
SDN ORGANISATIONS
SDN ON THE RISE Cloud Computing
Bringing together a community of vendors and developers to create a framework for an open source project that will enable a widespread adoption of SDN.
A user-driven organisation dedicated to the promotion and adoption of SDN through open standards development. OpenFlow is one of the standards that has originated from the ONF. SDN Central offers a unique perspective on the market, early access to use cases, and opportunities to speak with thought leaders looking to build new solutions and solve complex networking problems.
