CESNET Research Department Continent-wide Fibre Footprint Colchester October 18th, 2004University of Essex meeting 2 National LambdaRail in USA The first National LambdaRail link was lit in 2003 l 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. l Phase two, which is expected to be complete by May or June 2005, will cover the southern region of the United States. l Cisco (Pirelli) transmission equipment, 4x10Gbps, expandable

CESNET Research Department Continent-wide Fibre Footprint Colchester October 18th, 2004University of Essex meeting 3 Crucial Importance l 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 1969U.S. Department of DefenseARPAnet –the National Science Foundation worked on NSFnet in the late 1980sNSFnet

CESNET Research Department Continent-wide Fibre Footprint Colchester October 18th, 2004University of Essex meeting 5 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. l Internet2 has established the National Research and Education Fiber Company (FiberCo) to help these groups acquire regional fiber.National Research and Education Fiber Company

CESNET Research Department Continent-wide Fibre Footprint Colchester October 18th, 2004University of Essex meeting 6 Lengths of dark fibres in RENs l More than km in Europe (plus some fibres for GN2 and GN2 testbed) l About km in USA (including National LambdaRail) l About km in Canada l NFF contracted in Australia ….

CESNET Research Department Continent-wide Fibre Footprint Colchester October 18th, 2004University of Essex meeting 7 GN2 starting position l The second continent-wide CEF network? l … but winner takes the all! l More advanced transmission technology? l More fibre miles than NLR ? l Ability to add dark fibre lines instead of leased services (lambdas) each year? l Transition of NRENs and academic MANs to dark fibres with GN2 support? l Testbed for GN2 dark fibre transmission technology and switching upgrade?

CESNET Research Department Continent-wide Fibre Footprint Colchester October 18th, 2004University of Essex meeting 9 GN2 topology l CESNET, Pionier, SANET, Switch, …. are CEF Networks now l Near over Border (NoB) connections of CEF Networks are mostly technically simple, cheap, natural and advantageous (low cost international traffic, local peering,….) l GN2 will be overlaying (the second) dark fibre infrastructure l 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,…. )
