  1. ORNL’s FutureNet Infrastructure W. R. Wing Network and Cluster Computing Computer Science and Mathematics Computing & Computational Sciences Dir

  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 were received • UltraScience Net (DOE circuit-switched research net) • CHEETAH [National Science Foundation (NSF) circuit-switched research] • ETF (NSF extension of TeraGrid) • ORNL pooled funds to build capacity rather than lease it

  3. Bought 20-year indefeasible right of use leases with Qwest (Red) and TVA (Yellow)

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

  5. 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

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

  7. CHEETAH: MPLS/GMPLS-based research

  8. Of course, the real goal has been connectivity

  9. So, how are we really doing it? • Dense wavelength division multiplexing (DWDM) transport gear from Ciena • Latest (3rd-generation) /w 25-Ghz lambda spacing • C-band tunable transponders • CoreDirector switches for lambda and sub-lambda switching • Supports Generic Framing Procedure (GFP) mapping, link capacity adjustment scheme (LCAS), virtual concatenation (VCAT)

  10. The project isn’t finished • Adding extensions to Memphis, Oxford, and Starkville • Pick up University of Memphis, Ole Miss, and Mississippi State • Adding an extension through Cincinnati to Columbus • Providing support for NASA lambda through Nashville to Atlanta

  11. It will look like this when complete
