David Foster, CERN LHC T0-T1 Meeting, Seattle, November November Meeting David Foster SEATTLE

David Foster, CERN LHC T0-T1 Meeting, Seattle, November 2005 Scope for new attendees The “simplest” part of LHC networking is getting the data from CERN to the Tier-1 centers. It involves however, a number of stakeholders, initiatives and infrastructures. We want to understand how this part should be handled from a production network perspective. But this is only one part of the overall problem and we don’t deal with T1-T2 production networking issues …. Yet.

David Foster, CERN LHC T0-T1 Meeting, Seattle, November 2005 Current State We have had a number of meetings and agreed on an overall approach with many open questions. –Some results have been published –And we have a wiki site for gathering operational information. As we move more and more towards providing an production infrastructure needed for service challenges in 2006, many basic issues still remain. The purpose of todays meeting is to review what has been done since the last meeting and decide what remains to be done

David Foster, CERN LHC T0-T1 Meeting, Seattle, November 2005 Last Meeting Summary T0/T1 Top Items Version 2 of the document. (DF) –Complete some details and word for increased clarity in scope. Where do we go from here? 1.Security (Led by: UK – Robin Tasker) What should be done? Agree a plan for ACL/Firewall protection. 2.OPN IP Network Design (Led by: CERN Edoardo Martelli) Agree an IP design and routing based on a specific topology. –Backup routes. 3.Monitoring (Led by: US-LHCNet ….. Shawn Mckee …..) Definition of what is needed, metrics and techniques –Agree a framework and agree a design based on detailed hardware infrastructure understanding and monitoring technology. 4.Network Operations (Led by: DANTE Roberto Sabatino) Agree a process for problem determination and resolution. –Pilot –LCG/EGEE GOC, ROC, CIC interface, T1 interface –Organise a small number of multiple noc’s –Organise Border equipment to the OPN Mailing lists by Aug 20th First draft reports by November.
