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

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

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

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

Of course, the real goal has been connectivity
9 Wing_11/2006
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 Wing_11/2006
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
