Research Networks Test Trans-Atlantic 100G Connection for LHC

Leading research networks supporting CERN's Large Hadron Collider in Switzerland are testing a 100G trans-Atlantic link for transporting the massive data sets associated with the project. Currently, up to fifteen 10G links over different paths are used in concert to move the data.

In March, the Department of Energy’s ESnet, Internet2, CANARIE, G√ČANT, NORDUnet and SURFnet began testing a leased  100 Gbps connection between Amsterdam (Netherlight Open Exchange) and New York. The four-week test was conducted in collaboration with LHCONE, the LHC Open Network Environment.

ESnet reports positive results from the Advanced North Atlantic 100G Pilot. A saturation test over 10 minutes yielded a 99.9 percent utilization with no loss, no errors.  A 24 hour test at 50 Gbps, carried over 540 terabytes of data with no loss and no errors.
