OpenFlow @ Google - Urs Hoelzle, Google

Honestly, everyday I'm continually impressed by posts describing the internal technology powering Google. Having an abstraction layer like this for global deployment couldn't be more convenient. With the news about Facebook the other day, I watched a talk on OpenFlow ( link to this video ) and the fact that they have a test suite they can plug into continuous integration in order to see if your commit breaks your application in any network situation is incredible. I'd love to sign an NDA and just talk to the teams working on these projects for hours. Truly impressive work.

For those interested, Google has been using OpenFlow for some time now. This presentation by Urs Hölzle is about a year old: link to this video Slides: link

…ire international internal backbone (more traffic than public facing) to this model1. The issue at the moment is that there isn't lots of OS options and subsequently very little hardware support. Google developed their own hardware (despite preferring to have bought it2) and my understanding is they wrote their own software too. 1 link 2 link to this video…
