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

Grid Challenges for Networks Router Routed IP Network Router “layer-2” split out of wavelength [e. g. Ethernet] Grid applications will stress the network and need reservable/scheduled access to better 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.

Technical Network Liaison Committee • Terms of reference § SLAs – – To approved the SLSs which will be delivered by GEANT and NRENs. To present, disseminate and discuss prosed SLAs. To approve SLA monitoring procedures. To receive and assess reports network performance against the SLAs. § Network services – To agree recommendations for deployment of network services. – To receive repoprts on the proposed network services. – To receive requests from the EGEE team for new features. § Operational interface – To present formal EGEE requirements and use cases to GEANT/NRENs – To present EGEE traffic usage monitoring for assessment of the network usage.

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

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. SA 2 and JRA 4 Activities work in a long term perspective. We need inputs from the EGEE application layer. French Federation meeting - Lyon 11 June 2004 - 23
