Title: CERNs external networking update

CERNs externalnetworking update
  • Olivier Martin, CERN, Switzerland

What is new in Europe (1)
  • GEANT started to offer 10G access
  • GARR (Italy) was the first NREN to use it
  • Netherlands, Spain, Switzerland will follow
  • and, more surprisingly, Hungary, Poland,
  • Increasing number of National Research and
    Education Networks (NREN) moving towards dark
    fibre based networks, e.g.
  • Switzerland, Poland, Czech Republic, Netherlands,
    Slovakia
  • However, there is no general agreement on a
    European wide universal solution

3

What is new in Europe (2) (Testbeds)
  • NSFs Translight project proposal funded for an
    initial period of one year (from 4/1/03)
  • Includes new 10G lambda to Amsterdam for
    Internet2/Abilene, Canarie, GEANT, Surfnet
  • Contributes at the level of 25 to a 10G lambda
    to CERN also co-funded by DoE through Caltech as
    well as DataTAG US Line Consortium.
  • Metropolitan optical networking testbeds, e.g.
  • CzechLight, Netherlight, UKlight, VTHD
  • EU funded networking testbeds, e.g.
  • ATRIUM, DataTAG, LION, MOICANE (FP5)
  • ATRIUM-II, GARDEN, GRANDE (FP6)
  • Next Generation GEANT (1/1/2005) may include
    testbed(s)
  • as overlay network(s), is that a good idea?
  • as separate network(s)

DataTAG Mission
TransAtlantic Grid
  • EU ? US Grid network research
  • High Performance Transport protocols
  • Inter-domain QoS
  • Advance bandwidth reservation
  • EU ? US Grid Interoperability
  • Sister project to EU DataGRID

9
Main DataTAG achievements (1)
  • GLUE Interoperability effort with DataGrid, iVDGL
    Globus
  • GLUE testbed demos
  • VOMS design and implementation in collaboration
    with DataGrid
  • VOMS evaluation within iVDGL underway
  • Integration of GLUE compliant components in
    DataGrid and VDT middleware

10
Main DataTAG achievements (2)
  • Internet landspeed records have been beaten one
    after the other by DataTAG project members and/or
    teams closely associated with DataTAG
  • Atlas Canada lightpath experiment (iGRID2002)
  • New Internet2 landspeed record (I2 LSR) by
    Nikhef/Caltech team (SC2002)
  • Scalable TCP, HSTCP, GridDT FAST experiments
    (DataTAG partners Caltech)
  • Intel 10GigE tests between CERN (Geneva) and SLAC
    (Sunnyvale) (Caltech, CERN, Los Alamos NL,
    SLAC)
  • New I2LSR 2.38Gbps sustained rate, single TCP/IP
    flow, 1TB in one hour (S. Ravot/Caltech)
  • IPv6 (CERN Caltech)
  • 983Mbps between CERN Starlight
  • Tests with Japan
  • Near Gbps performance on 400ms RTT path
