  4. Next year’s transatlantic link • A call for tender is starting with the following objectives: • increase the transatlantic bandwidth to OC-12c (612Mbps) • move the Chicago PoP to the STARLIGHT • keep T3 commercial Internet access, but have an additional (backup?) access in Europe • keep (ATM) connectivity to the STARTAP • aim at direct peerings with North American R&D networks at the STARLIGHT over Gigabit Ethernet • All this is a natural extension of the existing setup CERN Update & DataTAG Project

  5. Dedicated lambda for research • What is new is that the call for tender also includes an option for a 2.5 Gbps transatlantic lambda, which will be dedicated to Grid applied network research • The aim is to have a dedicated testbed where new things can be tried out without affecting production traffic • One of our major concerns is tcp/ip performance over large bandwidth*delay networks • Single vs multi stream performance • Auto-tuning CERN Update & DataTAG Project

  7. The DataTAG Project

  8. DataTAG project • Transatlantic lambda dedicated to research (no production traffic) • 2.5 Gbps lambda between Chicago and Geneva • Primarily to connect GRID initiatives in Europe and North America • European partners: PPARC (UK), INFN (IT), University of Amsterdam (NL) and CERN, as project coordinator • The budget is 3.9 MEUR CERN Update & DataTAG Project

  9. UK SuperJANET4 NL SURFnet GEANT IT GARR-B DataTAG project NewYork Abilene STAR-LIGHT ESNET CERN MREN STAR-TAP CERN Update & DataTAG Project

  10. DataTAG Workplan • WP1: Provisioning & Operations (CERN) • Will be done in cooperation with DANTE • Two major issues: • Cost, can we afford it? • Routing, how can the DataTAG partners have transparent access to the DataTAG circuit across GEANT and their national network? • WP5: Information dissemination and exploitation (CERN) • WP6: Project management (CERN) CERN Update & DataTAG Project

  11. DataTAG Workplan (cont) • WP2: High Performance Networking (PPARC) • High performance Transport • tcp/ip performance over large bandwidth*delay links • Alternative transport solutions • End to end inter-domain QoS • Advanced network resource reservation CERN Update & DataTAG Project

  12. DataTAG Workplan (cont) • WP3: Bulk Data Transfer & Application performance monitoring (UvA) • Performance validation • End to end user performance • Validation • Monitoring • Optimization • Application performance • Netlogger CERN Update & DataTAG Project

  13. DataTAG Workplan (cont) • WP4: Interoperability between Grid Domains (INFN) • GRID resource discovery • Access policies, authorization & security • Identify major problems • Develop inter-Grid mechanisms able to interoperate with domain specific rules • Interworking between domain specific Grid services • Test Applications • Interoperability, performance & scalability issues CERN Update & DataTAG Project
