Interop 2012 will feature an OpenFlow plug-fest and lots of rhetoric. What I’m looking for is real use cases, mature products, and actual implementation. I’d like to see an SDN-based data center fabric for example — perhaps IBM and NEC will have something to show. Mobile devices and BYOD policies will drive a lot of campus LAN chatter this year. I expect to hear a good deal about network access control, wired/wireless convergence, application controls, location awareness.”]
