  17. Abilene – October, 2002 • IP-over-DWDM (OC-192c) and IP-over-SONET backbone (OC-48c) • 50 direct connections (OC-3c  10-Gbps) • 4 (soon 6) OC-48c & 1 Gig Eth connections • 2 10-Gbps (10 Gig Eth) connections pending • OC-192 SONET also supported • 23 connections at OC-12c or higher • Number of ATM connections soon down to 7 • 219 participants – research univs. & labs • All 50 states, District of Columbia, & Puerto Rico • Expanded access • 54 sponsored participants and 25 state education networks

  18. Next Generation Abilene • Partnership with Qwest extended thru 2006 • Juniper T640 routers selected for backbone • 10/11 next generation router nodes in place; 12th location pending • 2 racks in each location (Juniper T640 router & 4 measurement servers) • OC-48c SONET interconnects to Cisco 12008 routers • Very pleased to date with new router performance and interoperability with 1st generation backbone • 10-Gbps backbone  deployment has started this Fall • Transcontinental 10-Gbps ’s: 6 ’s connected to network • DC-NYC-Chicago-Indy-KC-Sunnyvale CA-Los Angeles • First  outage (3.5 hours): fiber cut in NYC • ITEC network performance validation test: 8 Gbps of 2-way traffic (v4 and v6 mix) transmitted without loss or reordering – Sunnyvale to San Diego

  19. Next Generation Abilene – more • Incremental, non-disruptive transitionUpgrade Schedule Overview • Aug/Sep – New backbone routers installed • Sep/Oct – ‘First wave’ turn-up • Fall 2002 – Connector & peer circuits migrated to new routers • 2003 – Remaining 10-Gbps ’s commissioned • Advanced service foci • Native, high-performance IPv6 • Enhanced, differentiated measurement • Rapid restoration for resiliency

  20. Native IPv6 deployment • Abilene is now running native IPv6 over the entire Cisco 12008 and Juniper T640 backbone • Dual stack mode • IS-ISv6 used for internal routing • Significant number of peers and connectors already have converted • Tunnel support consolidated • IU-NOC provides support for existing tunnels; Not accepting any new tunnels • Abilene provided addressing • 2001:468::/35 from ARIN for participants – 63% allocated • 3ffe:3700::/24 from 6bone for SEGP / sponsored users • Native IPv6 (UCSD iGrid demo: 400 Mbps v6 SD-AMS) • Kudos to Abilene NOC, IPv6 WG, Cisco, and Juniper

  44. Remote Instrumentation and Data Analysis Large scientific projects increasingly draw on resources from many countries. Scientists can use high-performance networks for remote instrument control and to pool computing resources for data analysis, improving ease of use and lowering costs. • The Gemini Observatory – Twin Telescopes • An international collaboration (US, Australia, U.K., Canada, Chile, Argentina, Brazil) • NSF funds US participation Mauna Kea, Hawai’i, USA Cerro Pachon, Chile

  45. VLBI - Very Long Baseline Interferometry • Astronomers collect data about a star from many different earth based antennae and send the data to a specialized computer for analysis on a 24x7 basis. • VLBI is not as concerned with data loss as they are with long term stability. • The end goal is to send data at 1Gb/s from over 20 antennae that are located around the globe. Interesting: Successfully ran 788 Mbps sustained test between sites in U.S. Working on prototype experiment to test their ability to run data to Europe and Japan.
