Next year s transatlantic link l.jpg

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

Dedicated lambda for research l.jpg

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

The DataTAG Project


Datatag project l.jpg

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

Datatag workplan l.jpg

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)

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
