On September 15-16, 2014, the University of Michigan and the ATLAS Great Lakes Tier-2 center hosted the most recent LHCOPN (LHC Optical Private Network) / LHCONE (LHC Open Network Environment) meeting in Ann Arbor, Michigan, bringing together physicists, network engineers and network researchers to discuss issues and plans for LHC networking. The LHCOPN/LHCONE meetings are typically held every 4-6 months at various venues in Europe, North America and Asia and focus on providing effective solutions for supporting the network requirements of high-energy physics worldwide.
The meetings began in 2005 with the formation of the LHCOPN, which is a private IP network interconnecting the Tier-0 site at CERN with national-scale Tier-1 sites around the world. The LHCONE component was added in 2011 as the effort in LHC networking expanded to include supporting regional Tier-2 center networking.
This meeting focused on a number of important topics, including:
The group also decided to include other high-energy physics collaborations outside the LHC in the LHCONE network by agreeing to add the Belle-2 sites that are not members of LHC experiments. Additionally, the group agreed to push ahead on creating a point-to-point Network Service Interface-based test bed that both ATLAS and CMS can start testing. The meeting timeline and presentations are available here.
