UltraScience Net:A Lambda-Switching Testbed
Enough lambdas (2 initial) to make switching real Explore “Light-Paths” for high-end transport Connect four hubs close to large DOE science
users (but let the user labs pay last-mile costs) Hubs in Sunnyvale, Seattle, Chicago, Atlanta Provide an evolving matrix of switching
capabilities Separately fund research projects (e.g., high-
performance protocols, control, visualization) that will exercise the network and directly support applications at the host institutions

Initial Switch Selection (& why so many?)
Cisco 15454, White Rock, and Sequoia 16000 MSPP’s Pros:
Explicit Sub-lambda Switching (OC-12, OC-48) Can save configurations for fast switching Provide Gig-E connections
Cons: No GMPLS on Cisco
Ciena (Core Director) Pros:
Direct Sub-lambda Switching at OC1 granularity Can do Gig-E and Fiber Channel directly Industry leader in developing GMPLS Research partnership
Cons: SONET is expensive

Starlight Configuration (per ChicagoEngineering Meeting)
1) We will install 20-port GigE cards (GigE LM) cards at all sites2) Need “media converter” at Starlight (10Gig-E to OC192)3) Need media converter at Sunnyvale iff required by research programs4) All Starlight “local” customers arrive via Starlight switch5) Local storage server and control server not shown

Current Status
Contracts all placed or ready for placement and awaiting ORO review
Initial connectivity to Chicago in two-three weeks (via Atlanta)
MSPP hardware all on orderWhy has this taken so long?
-answer-These are VERY complicated contracts… (and)

Expected Time Line
NLR Chicago-Sunnyvale “first light” in late August (10-Gig, not SONET) We have negotiated test-use on that path Expect to be able to do traffic testing in
August–September time frame
NLR SONET circuits follow in October Expect full system (just) in time for
SC2004
![Page 15: DOE UltraScience Net Update](https://reader035.fdocuments.in/reader035/viewer/2022070400/56813521550346895d9c823b/html5/thumbnails/15.jpg)

Summary
Atlanta-Chicago link to be up this summer Connecting ORNL to it will initially be via Atlanta
Chicago-Sunnyvale paced by NLR Initial 10-Gig test circuit, OC192 SONET follows PNNL fiber schedule will pace their connection
Expect E-to-E tests by fall Expect user traffic before SC2004
