1. INFSO-RI-508833 Enabling Grids for E-sciencE www.eu-egee.org Service Provision Architecture TNLC Meeting ― Athens, 2005-04-21 Mathieu Goutelle (SA2, CNRS UREC)

2. Enabling Grids for E-sciencE INFSO-RI-508833 TNLC meeting - 2005-04-21 2 Provisioning of IP Premium Provide Premium IP to the EGEE applications, Needs extra development in EGEE: –Interaction between BAR and the NSAP, –Interaction between BAR and the middleware, –Interaction between the middleware and the applications. Needs extra development from NRENs: –Provide the NSAP (receives requests from BAR and answers back), –Provide the mechanisms to configure properly the network. Definitely not straightforward!

5. Enabling Grids for E-sciencE INFSO-RI-508833 TNLC meeting - 2005-04-21 5 Questions Will PIP be operational (PIP implemented, presence of NSAP) in some NRENs? What will be the PIP provisioning model for EGEE? –Static allocation for a long duration? –Dynamic allocation following requests from EGEE to the NRENs? What will be the network model for EGEE? –NRENs/Geant as a “black box”? –EGEE will have to take care of concurrent EGEE flows on the same backbone link?
