CERN’s externalnetworking update: 

CERN’s external networking update Olivier Martin, CERN, Switzerland

Slide2: 

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 (1)

Slide3: 

NSF’s 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) What is new in Europe (2) (Testbeds)
