SDN Deployment with OpenFlow

Defined by Open Networking Foundation OpenFlow is an open API that provides a

common instruction set for interacting with packet-forwarding hardware

It is a centralized Controller that separates Data Plane from Control Plane

A single Controller interacts with many switches and allows for quick, dynamic changes as network needs evolve
