SDN 101: What It Is, Why It Matters, and How to Do It

Despite all the buzz about software-defined networking (SDN), many organizations don’t yet have a clear idea of how it will benefit them. In this blog, I’ll tackle the what and why of SDN, and explain the different approaches you can consider. What: A Disruptive Approach to Network Control For the last quarter century, network devices […]

Programmability and SDN are not the same

Network programmability means democracy, means freedom, freedom to program across all layers and entities, software or hardware – depending on your needs. Is SDN required to have network programmability? Not at all. Does the SDN architecture leverage network programmability? Yes, of course.  So, why do many people equate network programmability and SDN?

The “Business” of Software Defined Networking

I admit it. I’ve grown weary of the debate about whether SDN includes network programmability or whether or not SDN can only be accomplished through NfV, or the relative merits of control plane / dataplane separation. I will leave those debates to others more focused on the technology itself.  Personally, I have been more fascinated […]

#EngineersUnplugged S2|Ep13: Software Defined Data Center + Cloud

In this week’s episode of Engineers Unplugged, Bas Raayman from EMC and Caroline Orloff from ServiceMesh take on “what is the software defined data center and how is it like/different from the cloud”? Let’s watch and see what they conclude: Welcome to Engineers Unplugged, where technologists talk to each other the way they know best, […]

OpenDaylight: Understanding the Value Propositions

The announcement today of OpenDaylight is big news.  Industry leading companies are partnering via Open Source to serve an emerging set of market needs: Operators: want affordable real-time orchestration and operation of integrated virtual compute, application, and network. Application Developers: want a single simple interface to the network.  Underlying details such as “router”, or “switch”, or “topology” can be a distraction they desire […]

Infrastructure Software: SDN makes network management a first class citizen

Back in May 2012 Mike Fratto predicted in his blog that SDN will be “Reborn in Network Management”. There is a lot of truth to his statement. The words “software defined” in “Software Defined Networking (SDN)” inspired people to rethink the overall control plane architecture of the network making the case for infrastructure software that […]
