Even more, assuming it can cross the adoption gap, it could fundamentally change the business models of networking vendors (maybe not in the way you’d like them to be changed). You can read more about my OpenFlow views in the article I wrote for SearchNetworking.
On the more technological front, I still don’t expect to see miracles. Most OpenFlow-related ideas I’ve heard about have been tried (and failed) before. I fail to see why things would be different just because we use a different protocol to program the forwarding tables.
