5 LHCOPN Design Information All technical content is on the LHCOPN Twiki: Therapy Process LHCOPN Meetings (every 3 months) Active Working Groups Routing Monitoring Operations Active Interfaces to External Networking Activities European Network Policy Groups US Research Networking Grid Deployment Board LCG Management Board EGEE
6 LHCOPN Background Started in 2004 with the intention of solving the T0- T1 problem Well scoped problem at that time Group Therapy sessions organised by CERN No central funding Today multi-domain operational management is THE major issue Responsibility Who me? Monitoring - Keep your hands off my network! Grid Interface Its always the network! Infrastructure can be improved Starting as a simple unprotected star insufficient for a production network but enabled rapid progress. Has become a reason for and has leveraged cross border fiber. 6 Excellent side effect of the overall approach.

8 Todays Stats 8
9 The Future Essential to arrive at an operational model using industry best practices. Monitoring/Resiliency/Redundancy all need to be improved. Important to keep capacity ahead of demand. Real life use will give us the traffic patterns. Additional routes could provide more opportunities for backup Opportunities to make better use of the GLIF community? GLIF is an excellent and very impressive initiative. GLIF has brought much attention to the excellent work being done world wide. But. (and this might simply reflect my own limitations) 9
10 Beyond LHCOPN LHC networking is organic and many opportunities exist for improving T1-T2 connectivity (and T1-T1 connectivity). Can GLIF play a role in this? 10
11 The Dark Side of the Fiber We (I) may say that GLIF is not Integrated nor a Facility By design to keep governance lightweight Control Plane advances will certainly help, but governance issues will remain. Connections depend on one-by-one bi-lateral/trilateral agreements It is not trivial to find key information What can be used? Under what conditions? For how long? At what quality level? How can GLIF contribute to production networks in general and LHCOPN in particular?
