2 22 Protagonisten DFN-Verein (Ch. Grimm, K. Schauerhammer) DESY (V. Guelzow, K. Ohrenberg) GSI (P. Malzacher) RWTH Aachen (Th. Kress, Rechenzentrum) SCC (B. Neumair)

3 Volker Guelzow | GridKa OB 13.5.2012 | Page 3 Hintergrund > Computingmodelle ändern sich > Paper zur T2 Vernetzung von I.Fisk/K. Bos > Internationales Treffen Lyon (Entstehung der Idee eines Prototyps LHCONE) > Treffen RENATER, GARR, DFN, DANTE in Rom und Paris (technische Lösung und Bestimmung der intl. Kosten) > Atlas hat Top10 Liste erzeugt (die 10 T2 sites + T1 sites stellen lt. K. Bos 75% der IT Kapazität) > CMS hat Top 15 Liste erstellt

4 Volker Guelzow | GridKa OB 13.5.2012 | Page 4 LHCone: proposed architecture RENATER DFN GARR Other NRENs ESNET/ USLHCNet GEANT EU-US capacity: Several 10G links - demand oriented Capacity reserved for LHC and according to demand T1 centre T2 (or T3) Dedicated network to connect T1‘s & T2‘s (&T3‘s)

5 Volker Guelzow | GridKa OB 13.5.2012 | Page 5 Intl. T2 network: proposed architecture > Financing of this structure is clearly a national matter – the federated architecture takes this into account > The architecture provides a scalable system, i.e. other ntl. LHC communities can easily join through their NRENs. > Architecture compatible with „normal“ IP structure > The system is relatively easy and fast to implement with known workflows (in the NRENs) > The system is connected with LHCOPN through the T1s however not violating the LHCOPN AUP
