49 9/15/2014 Belle II at KEK, Tsukuba, Japan • From presentation by Takanori Hara (KEK), [email protected] • Belle II is an experiment that is a “sibling” of the LHC – An e−e+ asymmetric-energy collider with extremely high luminosity • The amount of data to be handled by the experiment is comparable to the LHC (year 1 of Belle II = 2017)
50 9/15/2014 Belle II at KEK, Tsukuba, Japan • It has been ESnet’s long term experience that the network traffic generated by a science experiment is directly proportional to the amount of data generated by and experiment that is managed and analyzed by a distributed collaboration – Therefore, we can expect Belle-II to generate network at least equivalent to what we see today from the LHC – The experiment data handling is structured similarity to the LHC Belle II collaboration sites Asia N. America Europe ~45% ~15% ~40%
Japan :137 Canada : 17 Germany : 83 Korea : 34 US: 63 Italy : 59 Taiwan : 22 Austria : 14 Russia : 37 Poland : 11 India : 20 China : 15 Australia :18
51 9/15/2014 Belle II at KEK, Tsukuba, Japan • LHCONE for Belle II ?? – Belle II prefers to have a closed network like LHCONE – Configuring new VRFs for Belle II at each collaboration sites and related networks is difficult • many Belle II computing sites overlap with computing sites in LHC experiments and so it would be difficult to split between two VRFs • Belle II traffic shares the same bandwidth with LHC experiments – Like the LHC, the detector to data center paths will likely be provided separately • Traffic pattern is somewhat different from LHC (Japan→US/Europe, US → Europe are main) – Can Belle II join LHCONE?
– WEJ comments: • Most of the LHCONE VRF infrastructure is provided by the R&E network providers and is not paid for by the LHC experiments • Many of these same providers serve the Belle II sites • In my opinion there is no reason that Belle II should not use the LHCONE VRF infrastructure - perhaps renamed to HEPONE – as the High Energy Physics community is very similar in terms of sites across the different experiments • This will be discussed at the next several LHCONE meetings
