  1. DOE UltraScience Net Update ESCC/Internet2 Joint Techs July 21, 2004 W. R. Wing

  2. Talk Outline • Quick Review of What We About • Current Status • Expected Time Line • Control Plane

  3. 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

  4. Additional Bits and Pieces • Off-hours bandwidth via MPLS on ESnet • Core SONET Switches at the four hubs • Edge MSPP boxes for additional services • Gigabit Ethernet-attached storage • A control plane to tie it all together • A scheduler to make it available

  5. Bits and Pieces Cont. • A progression of switching approaches • Study/compare MPLS(GMPLS), SONET, all optical • New all-optical technologies coming (e.g., laser tuning) • Local Storage • Logistical Storage Depot (prior to local application development) • Progression of experimental point-to-point transport technologies • Fiber channel • Infiniband

  6. ESnet CERN etc. NLR The Physical View From 50,000 feet ORNL Connector

  7. Seattle PNNL Starlight FNAL ANL Sunnyvale LBL SLAC ORNL Attached Sites Gig-E Attached Linux Storage Switches WhiteRock Mini-MSPP /w Gig-E MPLS-link via ESnet 2 x OC192 Global Architecture for DOE UltraScience Net Location Switch Type Interfaces Sunnyvale Cisco 15454 2 x OC192, 2 x OC48, 8 x Gig-E Ciena CD-CI 2 x OC192 Seattle Ciena CD-CI 6 x OC192 Starlight Ciena CD-Ci 8 x OC192 or 6 x OC192 and 16 x Gig-E + 2 x OC48 White Rock 1 x OC192, 8 x Gig-E Oak Ridge Ciena CD-Ci 2 x OC192, 2 x OC48, 8 x Gig-E White Rock 1 x OC192, 8 x Gig-E

  8. 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

  9. UltraScience Net Circuit Switching

  10. UltraScience Control-Plane: Phase I Seattle Core Director Core Director Chicago host VPN Sunnyvale host VPN VPN Core Director host IP network ORNL VPN Core Director host lambda VPN TL1

  11. Control-Plane • Phase I • Centralized VPN connectivity • TL1-based communication with Core Directors and MSPPs • User access via centralized web-based scheduler • Phase II • GMPLS direct enhancements and wrappers for Tl1 • User access via GMPLS and web to bandwidth scheduler • Inter-domain GMPLS-based interface

  12. CD-CI 10 x 1Gig-E (GigE LM) ESnet Switch Media Converter Starlight Switch 10Gig-E 10 x 1Gig-E (GigE LM) Starlight Configuration (per ChicagoEngineering Meeting) OC192 We will install 20-port GigE cards (GigE LM) cards at all sites Need “media converter” at Starlight (10Gig-E to OC192) Need media converter at Sunnyvale iff required by research programs All Starlight “local” customers arrive via Starlight switch Local storage server and control server not shown

  13. 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 order Why has this taken so long? -answer- These are VERY complicated contracts… (and)

  14. 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

  15. 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
