e-VLBI at IGRID2005!!

IGRID 05 US122 Dynamic Provisioning and e-VLBI Demo IGRID 05

Held at the University of California San Diego on September 28th and 29th.

Goals of Demo The main goals of the demo were:

The availability, performance, and reach of the Internet2 HOPI Testbed.
Show that the DRAGON implementation of the GMPLS control plane protocol stacks can dynamically reconfigure the Ethernet switching elements along the path to set up and tear down Ethernet framed light paths.
Inter-domain provisioning - the ability to provision light path services on an inter-domain basis, including the advertisement of service capabilities, compute and select the appropriate service path, scheduling characteristics and authorization policy between multiple administrative domains.
Application specific technologies - using e-VLBI show how the network can dynamically establish an application specific topology to support real-time data correlation from a globally distributed array of radio telescopes.
The e-VLBI demo is a trans-Atlantic and trans-Pacific real-time e-VLBI experiment at 512Mbps per station all pointing to the same quasar and transmitting the resulting data to the correlator at Haystack Observatory in Westford Massachusetts for real-time correlation.

Participating radio telescopes in the demo were: GGAO, USA, Kashima Japan, Onsala Sweden, Westerbork Netherlands and Westford USA.

e-VLBI Results The final results of the IGRID Demonstration was a real-time correlation using the antennas in Onsala, GGAO and Westford at 512Mbps. The transport protocol used was TCP and Jumbo frames were enabled. The resulting fringe plot was the result:
