Engineers from the Mid-Atlantic Crossroads (MAX), High-End Computer Networking (HECN) at NASA Goddard Flight Center (NASA/GSFC), Juniper Networks, Inc. and Fujitsu Network Communications have successfully completed a live trial of 40 Gbps connections between the University of Maryland campus and facilities in McLean, Va. using routing and optical equipment from Juniper Networks and Fujitsu. While most of today’s fiber-optic transmission infrastructure is limited to 10 Gbps, widespread implementation of 40 Gbps technology in live networks could help provide the scale needed to support the proliferation of advanced services such as on-demand high-definition video and real-time collaboration across the Internet. Equipment used in the trial included Juniper’s high-performance T1600 core routers and Fujitsu FLASHWAVE® 7500 metro/regional optical networking platforms, each equipped with 40 Gbps interfaces. The equipment was deployed in MAX’s metro-fiber network, and MAX teamed with long-time collaborator NASA Goddard for their expertise in flow rate testing. 40 Gbps test signals were successfully passed across 80 and 56 kilometer spans without any adverse impacts on production traffic running on separate wavelengths. Once the interface cards were installed and provisioned, they required no special configuration settings and encountered no compatibility issues between optical and routing platforms—proving that cutting edge 40 Gbps technology can be deployed quickly, efficiently and with minimal impact to network operations. “We currently use a 10 Gbps network path, partly provisioned by MAX, between our GSFC-based NASA Center for Computational Sciences (NCCS) supercomputer facility and the larger High-End Computing Capability supercomputer facility based at NASA’s Ames Research Center in California,” said HECN leader Pat Gary. “This year the NCCS upgraded its computing capability nearly threefold to 67 teraflops, and next year they expect to nearly double that capability. These supercomputers are used to run large models to simulate and better understand Earth’s climate and weather, the planet’s relationship with the sun, and the evolution of cosmic phenomena. With the extremely large data sets that must be transferred to other NASA sites and universities across the country for analysis, 40 Gbps links will allow us to improve the efficiency of our research work with real-time collaboration.” “As both an equipment vendor and research entity, Fujitsu is always looking for opportunities to support the research and education community,” said Jim Hintze, senior vice president of marketing at Fujitsu Network Communications. “The pioneering work that MAX and HECN are doing at the forefront of fiber optic transmission will help pave the way for enhanced research and learning opportunities. We are extremely pleased to have been a part of this breakthrough trial.” “As our customers introduce increasingly innovative and bandwidth-intensive services, technologies such as 40 Gbps can help them scale their networks quickly and efficiently,” said Opher Kahane, senior vice president and general manager of the High End Systems Business Unit at Juniper Networks. “While the T1600 router is already 100 Gbps-ready, the industry standards and specifications that make 100 Gbps possible are still underway. As this demonstration shows, 40 Gbps is ready for deployment today, so customers can immediately leverage this technology to increase the speed of their networks to meet the growing bandwidth demands of critical and efficient research programs.” Additional information on the equipment used, test configurations, and flow measurement results can be found at its Web site.
