SDN and OpenFlow Overview - Open, API and Overlay based SDN

Want to learn more? Join my GNS3 Practical SDN and OpenFlow Fundamentals course: goo.gl/OiMSjw
In this video we discuss the emerging SDN technology and how it is changing networking as we know it.
We discuss the various definitions of SDN including the OpenFlow protocol.
The three main definitions of SDN are:
1) Open SDN using OpenFlow
2) SDN via APIs
3) SDN via Overlays
