ORNL’s FutureNet Infrastructure: Enhancing Research Connectivity

DESCRIPTION

In 2003, ORNL faced connectivity issues with limited ESnet access and high costs. To improve infrastructure, three simultaneous network research awards were initiated: UltraScience.Net, CHEETAH, and ETF, pooling funds to enhance capacity. ORNL secured long-term options for fiber capacity and traded assets with National LambdaRail. The initiative led to the development of multiple research networks, including ULtraScience.Net and CHEETAH, utilizing advanced DWDM transport gear. Continuous expansions aim to connect vital institutions across the region, ensuring robust research capabilities.

  1. ORNL’s FutureNet Infrastructure W. R. Wing Computer Science Research GroupComputer Science and Mathematics Division

  2. History and context • In 2003 ORNL had a problem–poor connectivity: • ESnet connection only OC-12. • Qwest commercial OC-192 was costing $400,000/year. • Three simultaneous network research awards: • UltraScience Net (DOE circuit-switched research net), • CHEETAH (NSF circuit-switched research), • ETF (NSF extension of TeraGrid). • Pooled funds to build capacity rather than lease it.

  3. Bought options for 20-year IRU’son Tennessee Valley Authority fiber

  4. Bought a 20-year IRU with Qwest

  5. Initially lit Atlanta-Chicago and Nashville-Oak Ridge

  6. Arranged an asset trade with National LambdaRail for membership rights

  7. Infrastructure–Not a network • On it, we’ve built and added to three research networks and DOE’s operational network, ESnet: • DOE’s UltraScience Net (circuit switching with secure control and robust reservations), • NSF’s CHEETAH and Internet2’s HOPI (which will help study inter-domain issues), • ORNL’s connection to TeraGrid. • Options to connect to EVERYTHING worth connecting to.

  8. UltraScience Net: Fully-meshed, circuit- switched, dedicated-wave, research

  9. UVA ORNL NC State Atlanta CHEETAH: MPLS/GMPLS-based research DOE-USN NSF-CHEETAH

  10. But of course, the real goal has been connectivity FutureNet National Lambda Rail Internet2

  11. So, how are we really doing it? • DWDM transport gear from Ciena • Latest (3rd Gen) /w 25 Ghz lambda spacing • C-band tunable transponders • CoreDirector switches for lambda and sub-lambda switching • Supports GFP-mapping, LCAS, VCAT

  12. But the project isn’t finished • Lighting TVA fiber to Memphis, TN, and Starkville, MS • Pick up University of Memphis and Mississippi State • Adding an extension to Cincinnati to connect AVATEC • Providing NASA with a lambda through Nashville to Atlanta • Providing University of Alabama a lambda through Nashville to Atlanta

  13. Which will look like this when complete FutureNet National Lambda Rail Internet2
