The Object of the high energy physics (HEP) is to understand the basic properties of elementary particles and their interactions. High energy physics at the major accelerator sites where there are detector design, construction, signal process, DAQ and analysis is a large-scale enterprise conducted abroad. The size of collaboration is 100~2000 physicists. Therefore, the HEP community sets the pace for all in mapping out plans for handling enormous computational and data requirements as well as the required network infrastructure.
As an example, CMS(Compact Muon Solenoid) experiment at LHC(Large Hadron Collider) at CERN, Switzerland provides more than 2,000 scientists and engineers from 160 universities and laboratories in 36 countries. In Korea, 13 institutes are involved in CMS experiment. CMS collaborators participate in experiments that will accumulate more than 10 petabytes each during 2007-08 and this will rise to the exabyte range by 2015, introducing unprecedented challenges in data access, distribution and collaborative analysis. Therefore, CMS provides an example where GLORIAD meets the need of cutting-edge science. Approximately 40 percent of the physicists at work on the CMS collaboration call the US, Russia, China and Korea. They, along with the 2,000 scientists involved in CMS will need a high-capacity network to transmit results of these experiments by using data at regional data center. Korean CMS group is constructing Tier-1 regional data center at Kyungpook National University as a CMS Asia regional data center. Therefore, the GLORIAD network in Korea is absolutely needed for file transfer. The regional data center will be also used by other undergoing experiment such as Fermilab experiment and BNL experiment.
Other current HEP experiments at Fermilab and BNL face similar challenges on a “smaller but still large scale.” The high physics communities in Korea are already heavy users of APII and TransPAC. Therefore GLORIAD services and project the need for 300M/622M/1-2.5G capacity for major HEP centers in Russia, China and Korea in 2004/2005/2006 respectively.
