High-Energy Physicists Set Record for Network Data Transfer With a Sustained Data Rate of 186 Gigabits Per Second, High-Energy Physicists Demonstrate the Efficient Use of Long-Range Networks to Support Cutting-Edge Science


""Researchers have set a new world record for data transfer, helping to usher in the next generation of high-speed network technology. At the SuperComputing 2011 (SC11) conference in Seattle during mid-November, the international team transferred data in opposite directions at a combined rate of 186 gigabits per second (Gbps) in a wide-area network circuit. The rate is equivalent to moving two million gigabytes per day, fast enough to transfer nearly 100,000 full Blu-ray disks—each with a complete movie and all the extras—in a day.

The team of high-energy physicists, computer scientists, and network engineers was led by the California Institute of Technology (Caltech), the University of Victoria, the University of Michigan, the European Center for Nuclear Research (CERN), Florida International University, and other partners.

According to the researchers, the achievement will help establish new ways to transport the increasingly large quantities of data that traverse continents and oceans via global networks of optical fibers. These new methods are needed for the next generation of network technology—which allows transfer rates of 40 and 100 Gbps—that will be built in the next couple of years.

"Our group and its partners are showing how massive amounts of data will be handled and transported in the future," says Harvey Newman, professor of physics and head of the high-energy physics (HEP) team. "Having these tools in our hands allows us to engage in realizable visions others do not have. We can see a clear path to a future others cannot yet imagine with any confidence."

Using a 100-Gbps circuit set up by Canada's Advanced Research and Innovation Network (CANARIE) and BCNET, a non-profit, shared IT services organization, the team was able to reach transfer rates of 98 Gbps between the University of Victoria Computing Centre located in Victoria, British Columbia, and the Washington State Convention Centre in Seattle. With a simultaneous data rate of 88 Gbps in the opposite direction, the team reached a sustained two-way data rate of 186 Gbps between two data centers, breaking the team's previous peak-rate record of 119 Gbps set in 2009.""


The fast transfer rate is also crucial for dealing with the tremendous 
amounts of data coming from the Large Hadron Collider (LHC) at CERN:
