Global Crossing Network Supports Record in International Visualization

via PRNewswire

NAARDEN, Netherlands , Dec. 5 /PRNewswire-FirstCall/ -- Global Crossing(Nasdaq: GLBC) has made network performance history as the high-speed network provider for an experiment that set a world record in transatlantic visualization. Scientists from the Netherlands established a world record bygenerating the largest transatlantic real-time data stream to date for ultra-high-resolution visualization.

The record was set by SARA, the academic computer center in Amsterdam , which displayed a visualization stream of 19.5 Gbps between NetherLight, theGLIF Open Lightpath Exchange (GOLE) in Amsterdam , and San Diego in the US. This new benchmark for a real-time transatlantic data stream was establishedusing high-speed multiple 10-Gbps wave lengths supplied by Global Crossing tothe Dutch research network operator SURFnet.

During the experiment, network usage peaked at 19.5 Gbps, with a sustained rate of 18 Gbps -- a world record for bandwidth usage by one single application showing actual scientific content. The experiment was conducted at the iGrid 2005 conference in San Diego where the display was located. The conference included workshops and real-time demonstrations of research innovations in LambdaGrid infrastructure in support of advanced science applications. Global Crossing is one of the major providers of lambdas to the Global Lambda Integrated Facility (GLIF) community.

"This was a unique event which set out to test the limits of very high speed wide area networking to support data-intensive applications," said Paul Wielinga, SARA's business unit manager for high-performance networking. "The success of this experiment depended heavily on Global Crossing's high-speed transatlantic connections, as well as being able to source a virtual graphic card and a display that could handle a visualization with a resolution of 100 million pixels."

The high bandwidth usage was required to refresh the large "tiled" screen 20 times per second in order to achieve high levels of resolution. The output was viewed on a display of 55 screens of the Electronic Visualization Laboratory of the University of Illinois, resulting in a total resolution of 17,600 x 6,000 pixels. SARA will be taking this experiment forward in February next year when once again they will use Global Crossing as the backbone for running a high-resolution visualization and videoconferencing simultaneously.
