Editor's note: ESnet is a high-speed network directly connecting more than 40 major Department of Energy sites; it provides all of Fermilab's off-site network connectivity. ESnet also develops network technologies, which are used at Fermilab on a daily basis.
ESnet, which is based at Lawrence Berkeley National Laboratory, described their plans for the network in an announcement on the 10 August. Dubbed the Advanced Networking Initiative, it will serve as a pilot for 100 gigabit per second ethernet technology.
"We're moving to 100 gigabits because the standard today is 10 gigabits, and we already have individual streams of data that are bumping against that limit," said Steve Cotter, ESnet department head, in a recent interview. "We'd like to have a system out there that can handle more."
The Initiative will build 100 gigabit connections between the National Energy Research Scientific Computing Center at Lawrence Berkeley National Laboratory in California, Argonne National Laboratory in Illinois, and Oak Ridge National Laboratory in Tennessee. A fourth as of yet undetermined location in New York City will serve as a peering point - a sort of gateway - to international collaborators in Europe and Asia.
The Advanced Networking Initiative is being designed with the needs of some of today's largest international science collaborations in mind. For example, the next-generation archive of climate modeling data, which is maintained by the Program for Climate Model Diagnosis and Intercomparison at Lawrence Livermore National Laboratory in California, will contain at least 650 terabytes of data accessed by more than 2500 researchers worldwide. Likewise, once the Large Hadron Collider in Switzerland goes online, it will be able to generate in excess of 100 gigabits of data per second.
