  1. International Collaborations using Abilene and GEMnet- Overviews of GEMnet and Ongoing Projects - Masayasu YAMAGUCHI NTT Service Integration Laboratories

  2. Outline • Overview of Global Enhanced Multifunctional network (GEMnet) • Abilene-GEMnet Peering • Experiments on the peering • Distance education project (TIDE) • AccessNova project

  3. Global Enhanced Multifunctional network (GEMnet) • ATM-based broadband network testbed • Usage purposes: • Academic/research activities • Business incubation activities (but not commercial services) • Peering with Abilene aiming at global-scale academic/research activities

  4. Configuration of GEMnet Japan Tsukuba Labs. ★ Musashino Labs. ★ Makuhari ★ Labs. ★ 35M Yokosuka To USA Labs. ★ ★ R&D facility Kyoto Labs. Other access point ATM leased line for GEMnet To Malaysia CA*net II STAR TAP MREN Japan 6.5 M 33 M 6.5 M Abilene ★ (ATM, IP/ATM) San Jose USA West coast Facility Malaysia 1.5 M ★ East Asia R&D Facility (NTT MSC)

  5. Abilene-GEMnet Peering Seattle Present peering route (10M, since June 2001) New York Chicago Cleveland Sacrament Sunnyvale Kansas City New Jersey Denver Indianapolis 33Mbps (10Mbps for Abilene peering) 6.5M Los Angeles San Jose Abilene GEMnet West coast facility Atlanta CALREN2 To Japan Houston Preliminary route for Abilene peering via STAR TAP (April-May 2001, 5M was assigned) : ATM leased line for GEMnet : Abilene Core Router Node : GigaPOP or other NW

  6. Experiments on the peering Distance education project (TIDE) AccessNova project

  7. Trans-pacific Interactive Distance Education project (TIDE) Pacific JAPAN USA GEMnet Sunnyvale Abilene NTT San Jose Kyoto Univ. 10Mbps for IP ★ ★ CALREN2 Southern Ring NTT Musashino Labs.

  11. AccessNova ProjectCollaboration Frameworkbetween Asia and South America Japan • Furthest multimedia • broadband networks • Inter-cultural use of NW 17,230km (10,707 miles) Chile

  12. Broadband Connection between Tokyo and Santiago STAR-TAP Internet 2 (Abilene) 33 Mbit/s Tokyo AMPATH San Jose (10M for IP) REUNA2 2 Mbit/s Santiago

  14. Conclusion • Abilene-GEMnet peering enables world-wide broadband experiments. • TIDE project demonstrates the feasibility of interactive distance education using MPEG-2 video and audio. • AccessNova project shows the feasibility of video communications between Japan and Chile.
