SDN Blog

Rob Sherwood, Big Switch's CTO, gave a BrightTalk Webinar last week on Modern OpenFlow, and an overview of the open source components that play in it.As one of the one of the inventors of OpenFlow and author of FlowVisor (network virtualization using OpenFlow) in his Stanford days, Rob has been a part of SDN since its inception.  In this talk, he lays out a few hallmarks of SDN as it matures:...

As data center networks transition to modern designs to meet demands of cloud computing, data analytics and 4G/LTE mobile services, the corresponding traffic monitoring networks also need to transition to next-generation designs.  Traffic monitoring is necessary for variety of reasons, including network troubleshooting, network performance monitoring (NPM), application performance monitoring ...

I just got back from this year's Open Compute Summit and I have to say -- I was blown away.  Somewhere between the 3500 attendees, keynote talks from industry heavy weights, a surprise appearance from Mark Zuckerberg, and some hard numbers on open hardware cost savings ("Estimate over $1.2 billion over the last 3 years" - Frank Frankovsky, VP of Hardware Design and Supply Chain Operations at ...

In our previous blog post (Applications & Networks: Reunited Through SDN Innovations), we focused on latest innovations in software-defined networking – or SDN 2.0 – to bring networks to modernity. This is music to IT organizations because with SDN 2.0 networks they can deploy apps rapidly, significantly reduce OpEx and dramatically reduce CapEx. In parallel, the open-source initiative for...

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-ab...

Three truths: SDN is inevitable. SDN will dramatically simplify network operations. SDN will significantly reduce network equipment cost. By now, its clear that SDN is not a passing fad, so now you need to start contemplating how and to what degree you and your organization can or must digest this “next big thing.”There is no denying that new technology architectures, like SDN, can introd...

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 fo...

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 hint... 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 Network...
