  1. Challenges to address in the next future Apr 3, 2006 HEPiX Spring Meeting 2006 Enzo Valente, GARR and INFN

  2. Agenda • Challenges: • E2e with other networks • Connecting more regions [EV-HEPiX Spring meeting 2006]

  3. Agenda • Challenges: • E2e with other networks • Connecting more regions [EV-HEPiX Spring meeting 2006]

  4. Tier2 Center Tier2 Center Tier2 Center Tier2 Center Tier2 Center HPSS HPSS HPSS HPSS LHC Data Grid Hierarchy CERN/Outside Resource Ratio ~1:2Tier0/( Tier1)/( Tier2) ~1:1:1 ~PByte/sec ~100-400 MBytes/sec Online System Experiment CERN 700k SI95 ~1 PB Disk; Tape Robot Tier 0 +1 HPSS Tier 1 ~2.5 Gbits/sec FNAL: 200k SI95; 600 TB IN2P3 Center INFN Center RAL Center 2.5 Gbps Tier 2 ~2.5 Gbps Tier 3 Tens of Petabytes by 2007-8.An Exabyte within ~5 Years later.

  5. Current LHCOPN topology [EV-HEPiX Spring meeting 2006]

  6. GÉANT2 Topology [EV-HEPiX Spring meeting 2006]

  7. Esnet Topology Spring 2006 [EV-HEPiX Spring meeting 2006]

  8. LHCOPN – LHC Optical Private Network • Every Tier1 will be connected to the Tier0 with a direct 10Gbps “lightpath”. • Those lightpaths will be of different kinds: • single or concatenated layer 1 links (STM64, LANPHY, WANPHY) • layer 2 VLANs • Tier1s should also provide a dedicated backup link to Tier0, • during the startup phase (Service challenges) backup will be provided via routed paths (GN2, Esnet, Abilene, NRENs..). [EV-HEPiX Spring meeting 2006]

  9. Challenges • Multidomain L2VPN: something router manufacturers did not consider enough • Interoperability between platforms • An L2 path can be a security backdoor into someone’s LAN • An alternative using L3VPN was studied • A trusted relationship is needed • Complex setup • VPLS could be the solution to scale to T2 numbers [EV-HEPiX Spring meeting 2006]

  10. LHCOPN challenges • Security • The LHCOPN will bypass the security system (firewall, IDS...) already in place at every Tier; current technologies cannot deal with the requested bandwidth • Operations The ENOC is Network Co-ordination Service. It is required to: • look after network issues for EGEE and LCG • receive network TTS from NRENs, analyse them and provide relevant information to the GGUS who will then interact with the users • monitor the e2e status of the lightpaths and trigger the appropriate corrective actions • Monitoring • Several metrics, several different devices, and several OSI stack levels to monitor [EV-HEPiX Spring meeting 2006]

  11. Agenda • Challenges: • E2e with other networks • Connecting more regions [EV-HEPiX Spring meeting 2006]

  12. Networks, Grids and HEP • Next generation 10 Gbps network backbones are almost here: in the US, Europe and Japan • First stages arriving, starting now • Major transoceanic links at 2.5 - 10 Gbps since 2002-3 • Getting high (reliable; Grid) application performance across networks means: • End-to-end monitoring; a coherent approach • Getting high performance (TCP) toolkits in users’ hands • Working in concert with Internet2, Terena; the Grid projects and the Global Grid Forum • Network improvements are especially needed in SE Europe, Latin America; SE Asia, and Africa. • Removing regional, Last mile bottlenecks and compromises in network quality are now (in all world regions)On the critical path [EV-HEPiX Spring meeting 2006]

  13. ICFA-SCIC Closing the Digital Divide • Spread the message: “ICFA SCIC is there to help” • Help identify and highlight specific needs (to Work On) • Policy problems; Last Mile problems; etc. • Encourage Joint programs • Make direct contacts, arrange discussions with gov’t officials • ICFA SCIC is prepared to participate • Help Start, or Get Support for Workshops on Networks (& Grids) • Discuss & Create opportunities • Encourage, help from funded programs • Help from Regional support & training groups (requires funding) [EV-HEPiX Spring meeting 2006]

  14. Global connectivity Oct 2005 [EV-HEPiX Spring meeting 2006]

  15. BalticGrid NAREGI SEE-GRID OSG EUChinaGrid EUMedGrid EUIndiaGrid EELA A global, federated e-Infrastructure EGEE infrastructure ~ 200 sites in 39 countries ~ 20 000 CPUs > 5 PB storage > 10 000 concurrent jobs per day > 60 Virtual Organisations [EV-HEPiX Spring meeting 2006]

  16. EUMEDCONNECT [EV-HEPiX Spring meeting 2006]

  17. GRID initiatives around Europe • These initiatives aim to extendGrid Infrastructure for Research, which can become part of EGEE and be integrated with analogous initiatives in the Mediterranean (EUMedGrid), Balkans (SEE-Grid), North Europe (BalticGrid), Latin America (EELA) and Far-East Asia (EUChinaGrid). • Another purpose is to raise grid awareness and competences among the researchers, to make them able to profit of this new powerful tool, to foster collaboration with European and wordlwide projects and to promote scientific and industrial development in the area. [EV-HEPiX Spring meeting 2006]

  18. ALICEandEELA ALICE Topology October 2005 [EV-HEPiX Spring meeting 2006]

  19. SEEREN and SEEGrid [EV-HEPiX Spring meeting 2006]

  20. TEIN2 and EUChinaGrid Planned TEIN2 Topology November 2005 [EV-HEPiX Spring meeting 2006]

  21. GEANT2-ERNET and EUIndiaGrid • 45-155-622 Mbps from Europe to Mumbai • Then? [EV-HEPiX Spring meeting 2006]

  22. Angola Botswana DRC Kenya (KENET) Lesotho Malawi Mozambique (MoRENet) Namibia Rwanda S Africa (TENET) Swaziland Tanzania Uganda (RENU) Zambia Zimbabwe …others… General Internet access Connections to each other; and to Géant Abilene (Internet2) EUMEDCONNECT CANet (Canadian REN) TEIN2 (China, Japan, Malaysia) AARNET (Australian REN) …others… These countries ……..all want The UbuntuNet Alliance (S-E Africa) ..and they want it all very CHEAP !! [EV-HEPiX Spring meeting 2006]

  23. Interaction point with GEANT for grid issues • Technical Network Liaison Committee to address grid issues with GEANT/NRENs • Definition and establishment of Service Level Agreements for end-to-end services • Joint operation of ENOC (e-Infrastructure Network Operations Centre) • Deployment of network performance mgmt tools • Coordination of input to GGF Network Measurements Working Group [EV-HEPiX Spring meeting 2006]

  24. End

  25. Agenda • Challenges: • E2e with other networks • Connecting more regions [EV-HEPiX Spring meeting 2006]

  26. IPv6 • IPv6 already available – Standard • Research networks are IPv6 compliant • Grids need an high performance network • IPv6 is the value-added component [EV-HEPiX Spring meeting 2006]

  27. IPv6 • IPv6 can do everything you can do with IPv4, and IPv6 do it better • Public end-to-end network based on High performance forwarding • New generation routers support native IPv6 packet forwarding through hardware ASICs • Removing NAT and Private IP address reduces network delays [EV-HEPiX Spring meeting 2006]

  28. IPv6 • Collaboration with ASIA-PACIFIC drives to improve IPv6 in Europe • IPv6 will coexist with IPv4 • GRID Middleware needs to be IPv6compliant • Applications should be transparent [EV-HEPiX Spring meeting 2006]
