Presentation Transcript

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

  2. 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. GÉANT: Europe’s R&E Backbone

  4. 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. Fibre/Wavelength Footprint GÉANT2+NRENs 2004 [Black=λ, Red=Fibre]

  6. Fibre/Wavelength Footprint GÉANT2+NRENs 2008

  7. 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. European e-VLBI Test Topology Metsähovi Finland Gbit link Chalmers University of Technology, Gothenburg Jodrell BankUK OnsalaSweden Gbit link TorunPoland 2* 1 Gbit links DedicatedDWDM link Dwingeloo Netherlands MedicinaItaly

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

  10. ORIENT:opening the door for collaboration between Europe and China

  11. ORIENT –the shortest route from East to West

  12. ORIENT Applications • EUChinaGrid • Benefited from ORIENT/CSTnet connection….RTT difference:

  13. 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

  14. 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

  15. ORIENT and eVLBI APAN 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?

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