Understanding OpenFlow

The OpenFlow protocol is a key enabler in driving SDN solutions. OpenFlow is a standard protocol between data and control for remotely controlling the flow table of a switch or router:

Understanding OpenFlow

Figure 9: OpenFlow block diagram.

OpenFlow enables SDN controllers to define the flow of network packets across the network of devices supporting the OpenFlow protocol. OpenFlow defines a generalized flow table with a very flexible and generalized flow abstraction, Open control API, which enables remote control of layers1-7.

OpenFlow defines APIs for defining traffic flow and a framework for describing the flow state; hence, it can be viewed as the following.

OpenFlow as an API

OpenFlow is an outline semantic for defining flow characteristics of traffic and actions to take on the packets matching the defined characteristics.

OpenFlow as a control plane

OpenFlow provides a framework to define flow information and RPCs for a central SDN controller to program the flow state information. The...
