2 Wing_11/2006 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 Wing_11/2006 Bought 20-year indefeasible right of use leases with Qwest (Red) and TVA (Yellow)

4 Wing_11/2006 Arranged an asset trade with National LambdaRail for membership rights

5 Wing_11/2006 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 Wing_11/2006 UltraScience Net: Fully-meshed, circuit- switched, dedicated-wave, research

7 Wing_11/2006 CHEETAH: MPLS/GMPLS-based research

8 Wing_11/2006 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

11 Wing_11/2006 It will look like this when complete
