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 ?
