1. Connecting Academic Networks The ORIENT, TEIN and GÉANT Projects: International Research Networks John Chevers, DANTE International eVLBI Workshop Shanghai, 16 th June 2008

2. Connecting Academic Networks Presentation 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

3. Connecting Academic Networks GÉANT: Europes R&E Backbone

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

5. Connecting Academic Networks Fibre/Wavelength Footprint GÉANT2+NRENs 2004 [Black=λ, Red=Fibre]

6. Connecting Academic Networks Fibre/Wavelength Footprint GÉANT2+NRENs 2008

7. Connecting Academic Networks GÉANT2 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

8. Connecting Academic Networks Dedicated DWDM link Onsala Sweden Gbit link Jodrell Bank UK Dwingeloo Netherland s Medicina Italy Chalmers University of Technolog y, Gothenbur g Torun Poland Gbit link Metsähovi Finland European e-VLBI Test Topology 2* 1 Gbit links

9. Connecting Academic Networks

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

11. Connecting Academic Networks ORIENT: opening the door for collaboration between Europe and China

12. Connecting Academic Networks ORIENT –the shortest route from East to West

13. Connecting Academic Networks ORIENT Applications EUChinaGrid –Benefited from ORIENT/CSTnet connection….RTT difference:

14. Connecting Academic Networks ORIENT 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

15. 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

16. Connecting Academic Networks ORIENT and eVLBI APAN meeting June 2007, Xian, 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?

17. Connecting Academic Networks The Future GÉANT3 – service oriented network TEIN3 – next generation, new countries ORIENT -10Gbps? Continued support for eVLBI
