Scientists led by the California Institute of Technology (Caltech) have claimed a world record for data-transfer speed at 339Gb/s. The international team of high-energy physicists, computer scientists and network engineers boasted that the record is equivalent to moving four million gigabytes (or one million full length movies) per day, nearly doubling last year's record. They also reached another record for a two-way transfer on a single link by sending data at 187Gb/s between Victoria, Canada, and Salt Lake City.

The achievements, the researchers said, pave the way for the next level of data-intensive sciencein fields such as high-energy physics, astrophysics, genomics, meteorology and global climate tracking. For example, last summer's discovery at the Large Hadron Collider (LHC) in Geneva of a new particle that may be the long-sought Higgs boson was made possible by a global network of computational and data-storage facilities that transferred more than 100 petabytes (100 million gigabytes) of data in the past year alone.

The researchers, which included the University of Victoria and the University of Michigan, together with Brookhaven National Lab, Vanderbilt University and other partners, used wide-area network circuits connecting Caltech, the University of Victoria Computing Centre in British Columbia, the University of Michigan and the Salt Palace Convention Centre in Utah. While setting the records, they also demonstrated other modern methods such as software-defined intercontinental networks and direct interconnections between computer memories over the network between Pasadena and Salt Lake City.

As the demand for "Big Data" continues to grow exponentiallyboth in major science projects and in the world at largethe team said it looks forward to next year's round of tests using network and data-storage technologies that are just beginning to emerge. Armed with these new technologies and methods, the Caltech team estimates that they may reach 1Tb/s data transfers over long-range networks by next fall.
