  1. LCG Phase-2 Planning David Foster IT/CS 14th April 2005 Thanks to Dante, ASNet and ESnet for material presented at the T0/T1 Networking meeting in Amsterdam on 8th April 2005

  2. European Tier0/Tier1/Tier2 Connectivity Overview • A total of 7 NRENs serving Tier1 sites in Europe plus one in Asia Pacific • All currently have at least 1Gbps IP connections to CERN • 10Gbps lambda available on timescales ranging from July 2005 to autumn 2006 • Number, location and bandwidth requirements of Tier2 sites unclear to many NRENs

  3. GÉANT2 Project Partners

  4. RedIRIS (Spain) • Connecting the PIC Tier 1 site in Barcelona • Traffic crosses 3 domains prior to reaching GÉANT2: • PIC network • Anella Cientifica (Catalan regional network) • RedIRIS • Currently 1Gbps VPN is supported • Upgrade planned for RedIRIS connection to Catalan network, date TBD • No request has yet been received from PIC for 10G lambda • PIC requirement timeline unclear • 7 Tier 2 sites are known in Spain • Bandwidth requirement of Tier 2 sites unknown • Tier 2 sites connectivity varies from GE to STM-4 • Cost sharing TBD with Spanish ministry

  5. DFN (Germany) • DFN will connect the Tier 1 site at Karlsruhe to CERN via GÉANT2 • Presently 10G is available over GÉANT (Layer 3), providing LSP Karlsruhe-to-GÉANT-to-CERN • Testing is already taking place and high-datarate transfers have been shown Karlsruhe to CERN • Tier2 centres are not yet known so provision is unclear • Cost sharing: Karlsruhe will pay a subscription to DFN, a proportion of which will be passed to GÉANT2

  6. GARR (Italy) • GARR will connect the Bologna Tier1 site to CERN via GÉANT2 • 10Gbps lambda ring provided by GARR, connecting INFN-CNAF (Tier 1) and GÉANT2 PoP in Milan will be operational by September 2005 • By the end of 2005, multiple lambdas will be available from this site to GÉANT2, allowing as many 10Gbps connections as required • GARR connects Bologna Tier1 to other Tier1s via GÉANT2 • 12 Italian Tier 2 sites identified, all with DF to GARR backbone • 8 Tier 2 sites already have 1Gbps connection. All will have 1Gbps connectivity by September 2005 • GARR will bill INFN for all services provided, details of the cost sharing TBD

  7. UKERNA (UK) • UKERNA will connect the RAL Tier1 site to CERN via GÉANT2 • 2x1Gbps RAL-CERN via UKLight possible now • 10G lambda RAL-UKLight (switched port)-GÉANT2 by end 2006 • Cost will be addressed by UK national funding (discussions ongoing) -a proportion being channelled to GÉANT2 • Four distributed Tier 2 sites: NorthGrid, SouthGrid, ScotGrid, LondonGrid: bandwidth requirements unknown

  8. SURFnet (Netherlands) • SURFnet will connect the Tier1 site at SARA, Amsterdam • SURFnet6 will provide a 10G lambda to SARA by July 2005 • Initially 10G Lambda to CERN will be provided by SURFnet, later by GÉANT2 when available • Tier2 sites in the Netherlands will be connected via 10G lambdas by January 2006 • 1G lightpaths will be provided over NetherLight and/or GÉANT from Dutch Tier2s to non-Dutch Tier1s • SURFnet will absorb networking costs of the NL-access to CERN via GÉANT2 and all costs inside NL for accessing the Tier1 and Tier2s

  9. RENATER (France) • RENATER will connect the IN2P3 (Lyon) Tier1 site directly to CERN (not via GÉANT2) • RENATER will procure dark fibre between Paris, Lyon and CERN • 10G lightpath will be provided Lyon-CERN by July 2005 • Tier1-Tier1 traffic TBD • Traffic to/from the 3 French Tier 2 sites will pass over the RENATER network • Cost sharing TBD

  10. NORDUnet (Nordic Countries) • NORDUnet will connect the ‘distributed’ Tier1 site in the Nordic countries • Connectivity via lambdas can be provided by mid-2006 for all the sites concerned • Cost sharing TBD

  11. SWITCH (Switzerland) • The Tier1 site at CERN is connected directly to Tier0 • There are no Tier1 sites connected by SWITCH • The Tier2 site, CSCS has10GE if necessary • CSCS will connect directly to CERN (ie not via GÉANT2) • Cost of this connection will be borne by SWITCH

  12. European Tier1 SUMMARY • High data rate transfer tests Karlsruhe to CERN already underway • 10G available now (L3) from Bologna to CERN • Testing of 10G lambdas from Lyon and Amsterdam can commence from July 2005 • Amsterdam (and Taipei) will use Netherlight link to CERN until GÉANT2 paths are available • Testing of Barcelona link at 10G from October 2005 • Nordic distributed facility restricted to 1G until late-2006 when 10G available • RAL could operate between 2 and 4 x 1GE (subject to scheduling and NetherLight/CERN agreement) until late-2006 when 10G available. Interconnection of UKLight to GEANT2 might make an earlier transition to higher capacities possible.

  13. SC test bed @ Taipei

  14. Taipei Status • ASNet* runs one STM16 IPLC from Taipei to Amsterdam • One GE Local loop from Amsterdam to Geneva (via NetherLight LightPath Service), second GE is waiting to turn on (I already signed the xconnect order form) • will double the IPLC on July 1st (contract will be signed on May 27th) • ASCC LCG facilities now have multiple GE uplinks to ASNet’s core router; will be replaced by one or two 10GE during this summer vacation • ASNet connects (10GE*2 + STM64*n) to domestic backbone, a.k.a. TANet/TWAREN joint backbone, to reach T2’s in Taiwan. • Every T2 in Taiwan has it’s own 10GE link to the domestic backbone * ASNet (Academic Services Network, as#9264) is the network division and is also the network name that registered in APNIC.

  15. Asia Pacific Link Status • How many T2s in Asia Pacific region? • Taipei – Tokyo • STM-4 IPLC • 2*GE to APAN-JP (for JP Universities) • Will have GE to SiNet/SuperSiNet (for KEK) • IPLC should be increased before LCG production run. • Taipei – Singapore • STM-1 IPLC to SingAREN (National Grid Office of Singapore)

  16. Asia Pacific Link Status • Taipei – Hong Kong • STM-4 IPLC, will upgrade to STM-16 on Feb 1st, 2006 (contract already been signed on March 30th) • GE link to CERnet, GE link to CSTnet • CERnet : China Education and Research network • CSTnet : China Science and Technology network • Maybe have GE link with KOREN (still work with KOREN engineer)

  17. ASNet (Taiwan) Summary • ASNet connect the Taipei Tier1 site • Currently Taipei is connected via an STM16 link (IPLC) to Amsterdam, this will double in July 2005 • Currently traffic is routed over GE local loop and via NetherLight to CERN • Quality is assured by MPLS and PIP service • A move to a GÉANT2 connection Amsterdam-CERN is planned • A WDM solution is being considered, no decision as yet • Tier2 sites are connected in Taiwan (by 10GE to ASNet), Japan and China
