  2. Contents • Context overview • Networking activities summary. • Main tasks in progress French Federation meeting - Lyon 11 June 2004 - 2

  3. EGEE Applications • EGEE Scope : ALL-Inclusive for academic applications (open to industrial and socio-economic world as well) • The major success criterion of EGEE: how many satisfied users from how many different domains ? • 5000 users (3000 after year 2) from at least 5 disciplines • Two pilot applications selected to guide the implementation and certify the performance and functionality of the evolving infrastructure: Physics & Bioinformatics Application domains are for illustration only French Federation meeting - Lyon 11 June 2004 - 3

  4. Router Router Routed IP Network “layer-2” split out of wavelength [e.g. Ethernet] Grid Challenges for Networks • Grid applications will stress the network and need reservable/scheduledaccess tobetter than best efforts IP services. • Visualization and scheduled data delivery need guaranteed access to end-to-end channels • LHC raw data alone will need multi-gigabit channels to be available for weeks at a time • Network provision can itself be view as a class of Grid resource.

  22. IPv6 Uptake Study of the advantages of using IPv6 in Grid context: • DANTE deploying IPv6 (already started). • IPv6 is effective if deployed in all domains. The report will cover: • Study of features of IPv6, highlighting the ones of interest for Grids • Availability of IPv6 in NRENs and access networks • EGEE internal awareness of IPv6 Also: • Collaboration with 6NET • Possibility of building a testbed, needs to be agreed French Federation meeting - Lyon 11 June 2004 - 22

  23. Conclusion Network provision must itself be view as a class of Grid resource. This resource is highly dependent of the network services provided by the NRENs. SA2 and JRA4 Activities work in a long term perspective. We need inputs from the EGEE application layer. French Federation meeting - Lyon 11 June 2004 - 23
