Global Crossing Network Supports Record in International Visualization

via PRNewswire

John Legere , CEO of Global Crossing, said: "We are extremely proud of the proven capabilities of our global fiber network to support research experiments that are pushing forward the boundaries of international computergrids. Setting records of this nature requires a level of network performance and reliability that we consistently deliver to the global research andeducation community."

For this latest record-breaking experiment, the infrastructure between Amsterdam and San Diego consisted of a 20 Gbps connection set up in close cooperation with SURFnet via the GOLE's NetherLight in Amsterdam and StarLight in Chicago . The 2-D and 3-D data objects were rendered live on a powerful visualization cluster in Amsterdam and transported as a pixel stream via optical lambda networks to San Diego .

The availability of lambda networks opens the way for separation of the visualization "engine," or high-end graphical computer, from the high-resolution display. It enables real-time visualizations running at close to 20 Gbps over transatlantic wide area networks. This has other importantimplications, including allowing visualizations from a central facility to be distributed to distant locations without the need for data to leave aprotected, enclosed environment. The visualization of a medical procedure, for example, can be distributed as an intensive pixel stream without sensitive information leaving the hospital. This allows researches and scientists to view large data sets as a real-time image rather than have to store the data locally in order to be able to view it.

Mr. Wielinga commented: "This experiment is just the beginning of a concept, and we're considering other applications in the areas of astro- and high-energy physics that could use this networking model. None of this would be possible without access to dedicated high bandwidth capacity. We are pushing the limits of technology and we are now studying improved network protocols to overcome latency over long distances and to use even higher bandwidth more efficiently."

Global Crossing's collaboration with the research community in the pursuit of new standards for high-performance networking goes back to 2002 when GlobalCrossing supported SURFnet and its international partners to set a new intercontinental Internet2 land speed record. The record at that time was set by transferring the equivalent of the contents of an entire compact discacross more than 7,608 network miles between Alaska and Amsterdam in 13 seconds.
