I'm here in Las Vegas at Interop 2012, just finishing my day "0" (the show floor hasn't even officially opened yet). I've already listened to half-a-day's worth of talks/workshops about Software-Defined Networking, OpenFlow, and real-world, production use cases from a variety of companies (including ours!).It's exciting to see how far Software-Defined Networking (SDN) and OpenFlow have come. Last ... Read more

We’ve heard many times before the myth that Software-Defined Networks and OpenFlow aren’t ready for prime-time. Late last year and earlier this year, we heard Cisco's thoughts on OpenFlow (including from a VP of Data Center Switching): “We don’t think it’s production-ready.”A couple of weeks ago, this myth was completely busted by Urs Hoelzle’s keynote at the Open Networking Summit (...

Big Switch Networks announced its Open Software-Defined Networking (Open SDN™) architecture today. SDN has generated a lot of interest over the last few months and we have seen increasing amounts of SDN-washing with vendors taking existing solutions off their shelves, dusting them off and rebranding them SDN.

Server virtualization and networking seem to mix like oil and water in an enterprise operational environment. Wait - let me explain.I was with an enterprise customer last week who said, "You know – the real sticking we're seeing with our server virtualization builds is the network side of this." That was the fifth time I've heard that in the last four weeks.On the one hand, he's not alone. On th... Read more
