Though “data center” begins with the word “data”, everyone knows that the king in the data center is really the application. And to deploy apps, corporate IT has three main care-abouts:Deploy apps rapidlySimplify operational complexity (reduce opex cost)Reduce infrastructure cost (reduce capex cost)Unfortunately, the network has turned out to be the main bottleneck across all three care-abouts....

LinkedIn contacted me last week to say that Big Switch Networks made it onto this year's list of Top Ten InDemand start ups, meaning that their fancy data mining of all the LinkedIn traffic showed that we were one of the top small companies potential employees were looking at – specifically engineers.  I said, “that’s great,” which of course it is, but what's really great is that I found out...

This spring, we announced an aggressive plan to add open-source thin switching to our Open SDN product suite. We said we would extend and package the Indigo project commercially to enable a thin-switching platform for OpenFlow networks. We said we would open-source the latest innovations to Indigo Virtual Switch (IVS), which we deliver commercially as Switch Light for Linux. Along the way, we... Read more

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...

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... Read more

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... Read more
