The world’s biggest machine—the Large Hadron Collider—is used to make new discoveries about how our universe evolves. It outputs petabytes of data, shared with a global network of researchers in search of the Higgs Boson, extra dimensions, supersymmetry, and dark matter. Data sharing is being enabled by a highly intelligent Software-Defined Network (SDN) built with open source, including OpenDaylight and Linux. We spoke with the high-energy physics team at California Institute of Technology to understand the tech behind the LHC. Not only will their work have implications for science, but also for any enterprise, telco, or service provider faced with ever-increasing data volumes.
