We asked Doug a couple questions about SDN and this is what he said:

What is SDN?

The classic definition of SDN is really the separation of control and forwarding with a central (OS) environments.  Two other confusing definitions have also arrived as well, one is overlay architectures from companies like VMware, Plumgrid and Juniper. Lastly, adding an API onto a current platform has been the solution for many of the incumbent vendors.

Why are you excited about SDN?

It really changes the way that we “network” networks.  The modern problems we have to solve need to be looked at differently as some of the older protocols and techniques are not going to hold true.

How does the network of the future differ from today’s?

I would offer 3 predictions:

  1. Less “big iron” solutions
  2. Less reliance of proprietary single box solutions
  3. More basic connectivity solved in software
