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

It will look like this when complete
