GDB Rome April 2006 Report on LHC-OPN Meeting David Foster CERN IT-CS LHC GDB Meeting Rome, April 2006 David Foster, CERN

OPN Information • LHCOPN meetings started in 2005, 3 -4 meetings/year. • Objective: to define and coordinate the T 0 -T 1 networking. – Overall architecture document was produced in 2005. – Progress is tracked. – Working groups created to work on specific issues. • Many details in the slides attached to the meeting agendas. • https: //twiki. cern. ch/twiki/bin/view/LHCOPN/Web.

Services Delivered • High level review of T 1 internal networking (except pic) indicates that all have 10 G backbones and servers nominally connected at 1 G. • SC results indicate that for this purpose the network is able to sustain the required rates. • Clarification of experiment models now raises the issue of T 1 -T 1 traffic (especially Atlas) and T 1 -T 2 traffic (especially CMS). – OPN dealing with T 0 -T 1 and possibly T 1 -T 1 – Good National initiatives connecting T 2’s to National T 1’s but is international connectivity adequate?

T 0 Backbone • The LCG backbone is now fully operational with six Force 10 E 1200 in production. • Two of those E 1200 are dedicated to the connections to the Tier 1 s. Primary and Backup links are distributed between the two. • Two 10 Gbps links connect the LCG backbone directly to the CERN's external network for the L 3 connections via ESnet and Geant 2 -IP.

T 1’s • ASGC: Still connected with 2 x 1 Gbps transport via Surfnet – • • BNL: Still connected at L 3 via Esnet, but the deployment of the 10 G connections has started: CNAF: Connected with one dedicated 10 G lightpath provided by Geant 2 -E 2 E. FNAL: Connected with primary and backup 10 Gbps connections provided by USLHCnet. FZK: GN 2 has provided the lightpath from Geneva to Frankfurt. DFN is going to provide the remaining part up to Karlsruhe. – • • End Q 3 for 10 G RAL: Connection upgraded to four 1 Gbps lightpaths provided by Janet and Surfnet. – • • End Q 3 for 10 G PIC: still connected at L 3 via Rediris-Geant 2 -IP. – • End Q 2 for 10 G IN 2 P 3: Connected with 10 Gbps lightpath provided by Renater. NDGF: still connected at L 3 via Sunet-Nordunet-Geant 2 -IP. – • Start 2007 for 10 G Start Q 3 for 10 G SARA: 10 Gbps lightpath provided by Surfnet TRIUMF: still connected with two 1 Gbps connections provided by Canarie and Surfnet. – Start Q 3 for transit via GEANT from Amsterdam LHC GDB Meeting Rome, April 2006 David Foster, CERN

And … • Several sites now putting in direct connections to each other – FZK, CNAF and SARA will provide redundant paths to CERN through CDF links to each other. (Complete in 2006) • ESNet will provide additional path between NY and Chicago through their MPLS backbone • GEANT-2 has transponders to connect the required remaining sites – SARA, RAL, PIC, NDGF • NREN PC agreements on cost models and transport of Extra-GEANT data have concluded successfully.

Review of Activities • Routing – – Document produced and on Twiki. T 1 -T 1 traffic not excluded. Allowed IP addresses in the RIPE database. Need: BGP on all sites. • Security – Document has been produced. – Robin Tasker to liaise and agree with site security officers. – Report on feedback at the next meeting. • Monitoring – Document has been produced and published. – Perf. SONAR will provide the basic level-1 monitoring. – T 1 volunteers for prototype monitoring tests. • • Need to demonstrate value through volunteers. Will try and use this for demonstration purposed. – Piggyback on the perfsonar activity, but get more information? LHC GDB Meeting Rome, April 2006 David Foster, CERN

Operations • More clarity is needed to understand how to deal with operational issues. – Learning experience for everyone Dante/NREN/LCG – Dante deploying Perfsonar and integrate with ESNet, Internet 2, Canarie and Taiwan. – Schedule next workshop on handling scheduled interventions, backup and failover design and achieving availability targets.
