  1. The State of High Performance R&E Networks Aug 4th, 2001 Steven Wallace Indiana University ssw@iu.edu

  2. Good News (US) • Internet2/Abilene connecting over 200 institutions • 2.4 Gb/s backbone, still relatively underutilized • Well connected to other networks (currently carrying ~5% of world-wide routes) • Offering ITN service

  3. Good News ((US) cont.) • Production advanced services (IP multicast, QoS?, IPv6) • Change in conditions of use to allow K-20, libraries, etc. • Emerging Federal Lab routing policy (connection friendly, but not for inter-lab traffic)

  4. Good News ((US) cont.) • New Core Node in Chicago to participate in STARLight • Explicit recognition of End-to-End (E2E) performance challenges (I2 spending over $1M) • Expect to see upgrades to OC192 (10Gb/s) in some areas

  5. Continuing Challenges • E2E performance still not solid (E2E visibility difficult) • Advanced service coordination among networks difficult • Getting good planning information • QoS (not soup yet)

  6. European News • Similar to US, currently leap frog to 10Gb/s (also benefiting from fiber glut) • Slightly different model (a single network provides all Internet connectivity) • Key funding provided by EU (former US model) • Well organized

  7. Transatlantic News • Dante recently offered a tender for transatlantic connectivity • Wavelength based services (2.4Gb/s & 10Gb/s) • Less StarTap centric • 2.4Gb/s transatlantic for less $1M Euros/yr • 10Gb/s transatlantic for a couple/few $M Euros/yr

  8. Asia Pacific News • Much more complicated • Nothing really equivalent to Dante/GEANT Internet2/Abilene • More focus on IPv6 • Still capacity challenged

  9. Transpacific News • Wavelength based services coming soon • 2.5Gb/s relatively affordable (still quite a bit more than US-Europe) • Less effective at coordinating transpacific purchases (still prestigious to have your own US connection)

  10. GTRN (original talk) • Good story for US and Europe, emerging story for Asia Pacific • Great story for trans-pacific/atlantic capacity • What’s missing? • Global coordination of advanced services • Global capacity planning • Global purchasing coordination

  11. What’s Needed? • An inter-connecting network and organization focusing on: • Global coordination of advanced services • Global capacity planning • Global purchasing coordination
