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

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)
