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

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 !
