Connecting Academic Networks

The ORIENT, TEIN and GÉANT Projects: International Research Networks

John Chevers, DANTE

International eVLBI Workshop

Shanghai, 16th June 2008

Connecting Academic NetworksPresentation

• GÉANT2 –the R&E backbone for Europe– GÉANT services– GÉANT and eVLBI

• TEIN2 –a network for Asia-Pacific• ORIENT –connecting Europe and China

– ORIENT applications– ORIENT and eVLBI

• The Future

GÉANT: Europe’s R&E Backbone

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

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

ORIENT –the shortest route from East to West

Connecting Academic NetworksORIENT Applications

• EUChinaGrid– Benefited from ORIENT/CSTnet connection….RTT

difference:

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

Connecting Academic Networks

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

ORIENT and eVLBIAPAN meeting June 2007, Xi’an, China• eVLBI Demonstration• Facilitated through CSTnet connection• Connected China to Europe at 256Mbps• Demonstrated the first global eVLBI session• Successful press release• Hope for eVLBI science runs soon!

• Other Chinese observatories?

Connecting Academic NetworksThe Future

• GÉANT3 – service oriented network• TEIN3 – next generation, new countries• ORIENT -10Gbps?• Continued support for eVLBI
