There are plenty arguments going on around how making network equipment “dumb” and programming it from a centralised location will save a ton. Well, saving a ton it may be, but I would like to focus on what might be lost or compromised by doing so.
As an aside: looking at the evolution of the OF protocol, the amount of “stuff” that switches will need to be able to do to support it is increasing quite rapidly. Wonder how long will it take for the complexity to be back in the devices in force, just under a different banner?
