Previous Featured Projects
Real-time e-VLBI data correlation - August 2007 The e-VLBI community is using facilities of Pacific Wave and several different Pacific Wave participants to conduct real-time e-VLBI (electronic very long based inferometry)correlations from international telescopes. An example of this was the recent EXPReS project (Express Production Real-time e-VLBI Service) which conducted the first successful real-time correlation of e-VLBI data from Chinese and Australian telescopes, from Chinese and European telescopes, and from Australian and European telescopes. The observation was demonstrated before advanced networking experts at the 24th APAN (Asia-Pacific Advanced Network) Meeting in Xi'An, China.
Caltech's High Energy Physics Group - December 2006
Caltech's High Energy Physics Group is one of the major participants in the CMS collaboration at CERN's Large Hadron Collider (LHC). They are participating in the GLORIAD link bandwidth challenge sponsored by Ultralight partner KISTI. Through the use of Pacific Wave, Caltech intends to demonstrate high speed transfers of physics data sets between Caltech to KISTI in Korea. During the challenge they aim to maximize the utilization of the Pacific Wave connection to and from the Caltech CACR data center. End hosts involve a pair of quad AMD Opteron Newisys systems and Neterion 10G NICs. The traffic consists of a realistic mixture of streams: those due to the transfer of the TeraByte event datasets, and a set of background flows of varied character absorbing the remaining capacity. The intention is to simulate the environment in which distributed physics analysis will be carried out at the CERN LHC. Preliminary tests in February 2006 showed sustained usage of 6.67 gigabits per second over the Pacific Wave connection.
GEMNet2/NTT Labs - December 2005What do massive earth-hammering equipment in underground copper mines and high-precision, remote mountaintop astronomical telescopes in Chile have in common? Both were remotely operated by GEMNet2/NTT Labs staff in Tokyo at a December 2005 NTT Group Communications Expo. Through their participation in Pacific Wave, GEMNet2/NTT Labs researchers were able to use a 17,100km network path from two sites near Santiago, Chile to conduct their operations. Both the mountaintop astronomical site at Cerro Calan and the Andina underground mine near Los Andes were connected to University of Chile and the Reuna node in Santiago. From here, the path used RedClara, CENIC, Pacific Wave, and then the trans-Pacific GEMNet2 circuit to reach Tokyo.
Chile is the farthest country from Japan on the globe. The round trip time between the locations, using this Pacific-centric network path, was roughly 240ms. Total bandwidth utilization was roughly 20-30Mbps. In addition to the applications that operated the remote equipment, each site also used video conferencing to support real-time communications with the event goers in Tokyo.
