International Collaborations using Abilene and GEMnet- Overviews of GEMnet and Ongoing Projects - Masayasu YAMAGUCHI NTT Service Integration Laboratories
Outline • Overview of Global Enhanced Multifunctional network (GEMnet) • Abilene-GEMnet Peering • Experiments on the peering • Distance education project (TIDE) • AccessNova project
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
