GÉANT and its support for GRIDs GNEW 2004 Roberto Sabatino - DANTE Geneva, 15-16 March 2004 Technology • Connectivity from carriers • 10Gbps and 2.5 Gbps DWDM/wavelength services • SDH services • IP service via Juniper M-160 and M-40 Global Connectivity Korea CA*NET4-CHIC ABILENE-CHIC 34M 2xGE 2.5G ESNET NL renater UK 2.5G SINET CA*NET4 - NY 2.5G 2xGE GE ABILENE - NY ABILENE -WASH NY AT DE 2.5G GEANT Network Services • Premium IP • LBE - scavenger • L2 VPN-like services (to provide end-to-end GE) • and ipv6, multicast GRID co-operation activities • DATAGRID • network service (LBE) • network performance • DATATAG • network service (~ l2vpn - GE) • network performance • +others • DEISA • radioastronomy (VLBI) DATAGRID • Support for high volume data transfers at high data rates • Can make use of a more appropriate network service (LBE) • jointly designed and tested by DANTE+GN1+DATAGRID • deployed on GEANT • Can make use of a more appropriate protocol stack • verify its performance across GEANT DATATAG • Connectivity between CERN and Bologna • L2-VPN-like service in conjunction with CERN, GEANT and GARR. • GE service • High performance validated Others • DEISA • PoC from June 2004 • Connect super-computer centres in FR, DE, IT • GE with Premium IP • Radioastronomy • PoC whereby 5 telescopes send data to Dwingaloo • some experiments with promising results already started • potential of 14 telescopes EGEE • Strong relationship between GN1-2 and EGEE for development of network services for GRIDs • guaranteed by DANTE+NREN participation in EGEE • Definition of network services available to GRIDs and their invocation via appropriate middleware • starting with Premium IP • looking at circuit switched solutions • Network Performance measurement • a co-ordinated approach to retrieval of data What next for GEANT ? • Explore new (more appropriate ?) ways of supporting GRID network requirements • point-to-point circuit switched scenarios, based on GE • new service portfolio in GN2 ? (see presentation tomorrow) • new (hybrid) network architecture in GN2 ? Thank You !
