OpenFlow – Basic Concepts and Theory

In this post, David Varnum goes over some of the fundamental concepts of OpenFlow. He goes as far back as to distinguish the control plane from the data plane. David then goes into great detail about OpenFlow’s design and features. What inspired this deep dive into OpenFlow? At Networking Field Day in November, David saw a presentation from NEC on their ProgrammableFlow controller, a SDN product that uses the OpenFlow protocol. David found it “wildly impressive”, and wanted to get a better understanding of the protocol.


OpenFlow Is Dead. Long Live OpenFlow.

Tom Hollingsworth takes a look at the curious life of OpenFlow. This once hyped panacea has found a completely new life from its original purpose of replacing the forwarding plane programming method of switches. Tom compares it to the development of Viagra as originally being intended for high blood pressure. Company’s like NEC have taken OpenFlow, with their ProgrammableFlow derivative, and adapted it to a whole new set of purposes, in this case mitigating the spread of infections within networks. It’s always interesting to see an established tool reimagined with a new purpose.
