1
GÉANTand its support for GRIDs
  • GNEW 2004
  • Roberto Sabatino - DANTE
  • Geneva, 15-16 March 2004

GÉANT Topology November 2003
3
Technology
  • Connectivity from carriers
  • 10Gbps and 2.5 Gbps DWDM/wavelength services
  • SDH services
  • IP service via Juniper M-160 and M-40

Network Services
  • Premium IP
  • LBE - scavenger
  • L2 VPN-like services (to provide end-to-end GE)
  • and ipv6, multicast

6
GRID co-operation activities
  • DATAGRID
  • network service (LBE)
  • network performance
  • DATATAG
  • network service ( l2vpn - GE)
  • network performance
  • others
  • DEISA
  • radioastronomy (VLBI)

7
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 DANTEGN1DATAGRID
  • deployed on GEANT
  • Can make use of a more appropriate protocol stack
  • verify its performance across GEANT

8
DATATAG
  • Connectivity between CERN and Bologna
  • L2-VPN-like service in conjunction with CERN,
    GEANT and GARR.
  • GE service
  • High performance validated

9
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

10
EGEE
  • Strong relationship between GN1-2 and EGEE for
    development of network services for GRIDs
  • guaranteed by DANTENREN 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

11
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 ?
