The Earth is Round and OpenFlow Works

The sky is falling. The Earth is flat. OpenFlow is not robust. OpenFlow is a toy. OpenFlow is not deployable at large scale.All these charges (well maybe not the first two) are being leveled by incumbent networking hardware vendors desperately trying to slow down OpenFlow adoption, while they figure out how to continue extracting the same obscene margins from their customers.At the Open Network...

Progress in Portland: Charting a Path for OpenStack Network Services

OpenStack Networking @ Havana Summit, Portland, April 2013Last week, I attended the OpenStack Summit in Portland, Oregon and was extremely encouraged by many things: that the conference doubled in size since last year, the successful release of Grizzly, and by some really significant progress made with regard to network services by a diverse group of us network types.  Here are my takeaways f...

Making Sense of So-Called “SDN” Offerings

With the wide-range of Software-Defined Networking (SDN) announcements coming from various vendors large and small, I can only imagine the frustration customers must feel trying to make sense of this emerging market. There is no doubt that we’re are in a big hype cycle!  While vendor interest is certainly a great validation of the SDN market, someone needs to cut through the chaos and expla... Read more

Ruminations on OpenDaylight from the SDN Leader

Unless you were under a rock, you could not have helped but notice that the OpenDaylight SDN consortium project officially launched today after months of leaks and lots of speculation about what it is and is not, who is in and who is not, and what ultimately will be the benefit, if any, to end users. The broad embrace by the incumbent IT vendor community is an enormous validation of the Open SDN a... Read more

Intel Shares the Vision and Joins the SDN Team

Four years ago, we realized that traditional approaches to designing and building network infrastructure were no longer sustainable. We teamed up with some very sophisticated users who shared their challenges and a vision for an open and standards-based software-defined networking platform. With no installed base or legacy business to preserve, Big Switch had the luxury of starting with a clean sl... Read more

Why OpenFlow Hardware Control Matters in the Data Center

In the last week, there was some discussion about whether OpenFlow for physical switches matters for the data center. If some are to believe OpenFlow control for hardware switches is not only a bad idea, but also against the interest of users as well as switch vendors. http://bit.ly/TWQyus If you feel confused, you are not alone. Over the past year, at Big Switch, we ...

Networking Gen 2.0: Enabling a New Breed of Networking Startups with the Open SDN

Over the last 20 years, generations of networking startups have been spawned to address the inherent shortcomings of L2 and L3 networking architectures. It’s not that Ethernet and TCP/IP are broken, rather that they were invented in a time (1960’s & 70s) when the demands on the network were dramatically less complex than today.  If you look back, you can see this trend very clearly.Fi...

It's that time of year again

It's that time of year again - A chance to look back at what happened in 2012 and prognosticate a bit for 2013.2012 definitely will be rememebered as the year that defined Software-Defined Networking (SDN) from the ecosystem perspective as well as from the customer perspective.  Several SDN companies launched, including Big Switch Networks. The space even saw M&A with VMWare, Brocade, and... Read more
