National LambdaRail in USA

• The first National LambdaRail link was lit in
  2003
• Last month, NLR completed the first full
  East-West phase of deployment, which included
  links between Denver and Chicago, Atlanta and
  Jacksonville, and Seattle and Denver.
• Phase two, which is expected to be complete by
  May or June 2005, will cover the southern region
  of the United States.
• Cisco (Pirelli) 15808 transmission equipment,
  4x10Gbps, expandable

Crucial Importance

• Experts say NLR is the most ambitious networking
  initiative since two efforts considered crucial
  to the development and commercialization of the
  Internet
• the U.S. Department of Defense commissioned the
  ARPAnet in 1969
• the National Science Foundation worked on NSFnet
  in the late 1980s

Dark fibre connection of NLR users

• There is still a serious last-mile problem. It's
  great we have this nationwide infrastructure, but
  it can only be used if you have the fiber to
  connect to it.
• Internet2 has established the National Research
  and Education Fiber Company (FiberCo) to help
  these groups acquire regional fiber.

6
Lengths of dark fibres in RENs

• More than 20 000 km in Europe
• (plus some fibres for GN2 and GN2 testbed)
• About 33 920 km in USA
• (including National LambdaRail)
• About 6 700 km in Canada
• NFF contracted in Australia .

GN2 starting position

• The second continent-wide CEF network?
• but winner takes the all!
• More advanced transmission technology?
• More fibre miles than NLR ?
• Ability to add dark fibre lines instead of leased
  services (lambdas) each year?
• Transition of NRENs and academic MANs to dark
  fibres with GN2 support?
• Testbed for GN2 dark fibre transmission
  technology and switching upgrade?

GN2 topology

• CESNET, Pionier, SANET, Switch, . are CEF
  Networks now
• Near over Border (NoB) connections of CEF
  Networks are mostly technically simple, cheap,
  natural and advantageous (low cost international
  traffic, local peering,.)
• GN2 will be overlaying (the second) dark fibre
  infrastructure
• Should GN2 copy GEANT old IP topology?
• Some traditional GN2 lines will be redundant
• Delivering of long E2E lambdas will be crucial
  for NRENs from GN2, not neighbour country
  connection (Nordunet, SEEnet,. )

Lighting of dark fibre NIL approach

• Production lines G.652, 1550 nm, EDFA
• 189 km Praha Pardubice GE since May 2002
• 235 km Brno Ostrava GE since June 2003
• 235 km Brno Ostrava OC-48 in 4 months 2004
• Experimental lines G.652, 1550 nm, EDFA
• 286 km Praha Brno GE May 2004 (Raman)
• More wavelengths possible

20
NIL tests in laboratory

• G.652 fibre spools, EDFA Raman
• 325 km GE
• 250 km OC-48
• 252 km 2x 10 GE
• 290 km 10 G DWDM
• G.655 fibre spools (recently delivered)
• 302 km 10 G DWDM
• lower cost of dispersion compensation on 10 Gbps
