Activities Enabling Grids for E-scienc. E • SA 2 – Operational Interface EGEE Network Activities Enabling Grids for E-scienc. E • SA 2 – Operational Interface EGEE Network (Geant + NRENs) – SLAs EGEE Network (Geant + NRENs) – Technical Network Liaison Committee • JRA 4 – Network Performance Monitoring – Bandwidth Allocation and Reservation – IPv 6 These activities are by design building an important working relation between EGEE and the network providers (GÉANT + NRENs) INFSO-RI-508833 EGEE-3, Athens; Network Service Development & Resource Provision 2

TNLC Enabling Grids for E-scienc. E • Network Operational Interface between EGEE-NRENs – Agreement TNLC Enabling Grids for E-scienc. E • Network Operational Interface between EGEE-NRENs – Agreement with NRENs will be sought – TNLC approved proposed Operational Interface, discussed in MSA 2. 3 • SLAs are new to the NREN community and for EGEE – Plan for institution of SLAs described in DSA 2. 2 – The Qo. S experiment will help validate the proposed process • Agreed to limit BAR pilot to 2, perhaps 3 NRENs – That’s as many have agreed in principle to deploy software – Buy in from other NRENs can be achieved based on the success of the pilot INFSO-RI-508833 EGEE-3, Athens; Network Service Development & Resource Provision 4
