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.

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.

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,…. )
