With OpenFlow, the distinction between switches and routers doesn't really exist.

I hear they have different perspectives on this at Google.

... although the number of vendors and models of OpenFlow switch available off the shelf seems to continue to rise.

What I've observed is that few people who offer commentary on OpenFlow have taken the time to play with it. The deployment concerns, I think, are really software engineering and release problems. You don't want to depend on a custom OpenFlow controller that is only understood by one person who just got hired by someone else.

Software engineering discipline is not as common on the network administration side of the house as it is on the systems/devops or developer side. Some cultural shift is needed.
