Connecting Academic NetworksGÉANT Services
• IP Network– 34 countries in Europe– MPLS, QoS etc– Global reach
• Circuit network– Pre-provisioned– Typically 1Gbps– Europe and Transatlantic
• Lambdas– 10Gbps

Connecting Academic NetworksGÉANT2 and eVLBI
Europe• Dedicated 1Gbps circuits in place from:
– Jodrell Bank– Cambridge– Medicina– Torun– Effelsberg
• Expected soon:– Yebes (Madrid)– Onsala
China• Shanghai achieved 512Mbps in UDP tests to JIVE: fringes at 256 Mbps

TEIN2: a network for Asia-Pacific
-a regional success story
…continuing and expanding as TEIN3

Connecting Academic NetworksORIENT Applications (2)
• ARGO-YBJ– Solution difficult due to location– Now connected
• Large Hadron Collider– iHEP (Beijing) collaborations with IN2P3 (France)– Now using ORIENT
• INWA Grid– eSocial Science Research (market forces)– Using ORIENT and TEIN2

ORIENT: Earthquake Recovery Efforts
– Satellite images of disaster region transferred from JRC (Italy) to RSGS (China)
– Initially poor throughput– Solved by TCP tuning and the
addition of a second GE interconnect
– Images now being transferred
