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

The Open Networking Summit took place a week ago (April 16-18) in Santa Clara and showcased the tremendous progress the SDN and OpenFlow industry has made over the last few months. Several SDN users publicly talked about their implementations at this event including a couple of Big Switch Networks customers.Overwhelming attendanceThe previous event in October 2011 at Stanford was already superchar...

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. While these typically help established players preserve the networking status quo, thes... Read more

I’m incredibly excited to announce the release of Floodlight, a Java-based, Apache-licensed OpenFlow controller. As OpenFlow veterans, we’ve spent a lot of time working with OpenFlow controllers -- building enterprise-grade applications on them, ensuring compatibility with physical and virtual switches, defining APIs, measuring and improving performance, and generally pushing the limits of the...

There have been some recent discussions around the role of OpenFlow in the larger movement of Software-Defined Networking (SDN). Personally, I strongly believe OpenFlow plays a critical role in SDN – I don’t think it can be replaced by existing protocols/technologies. Over my next few posts, I’ll consider various technologies that are proposed as alternatives for use in SDN and see how well ... Read more

I’m waiting at the Las Vegas airport, catching my breath after several jam-packed days on the show floor of Interop. There’s a ton of email and other work stuff I really should be catching up on, but it’s been such an awesome show for OpenFlow that I’m compelled to write my first blog post here at Big Switch.Obviously, I’m biased, but it’s pretty clear Interop was a coming-out party fo...

If you attended the Open Networking Summit or the Applied OpenFlow Symposium last month, you could see that Software-Defined Networking (SDN) is gaining a lot of momentum. There may still be some nuances on its definition but it is pretty clear that everyone sees a need for it.For almost two decades, industry experts and hands-on networkers have worked hard creating protocols to solve L2/L3 issues...
