11. CESNET Research Department Introduction to technology testing www.ces.net Paris November 2th, 2004GN2 JRA4 meeting 11 Importance of Analysis l Deliverables should satisfy contract on GN2 project l Concurrently, results should be at world leading edge (from research and deployment point of view) l Analysis of current and expected leading edge in new technology deployment in research networking is important: first step follows

12. CESNET Research Department Introduction to technology testing www.ces.net Paris November 2th, 2004GN2 JRA4 meeting 12 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) 15808 transmission equipment, 4x10Gbps, expandable

13. CESNET Research Department Introduction to technology testing www.ces.net Paris November 2th, 2004GN2 JRA4 meeting 13 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

14. CESNET Research Department Introduction to technology testing www.ces.net Paris November 2th, 2004GN2 JRA4 meeting 14 NLR Topology

15. CESNET Research Department Introduction to technology testing www.ces.net Paris November 2th, 2004GN2 JRA4 meeting 15 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

16. CESNET Research Department Introduction to technology testing www.ces.net Paris November 2th, 2004GN2 JRA4 meeting 16 Lengths of dark fibres in RENs l More than 20 000 km in Europe (plus some fibres for GN2 and GN2 testbed) l About 33 920 km in USA (including National LambdaRail) l About 6 700 km in Canada l NFF contracted in Australia ….

17. CESNET Research Department Introduction to technology testing www.ces.net Paris November 2th, 2004GN2 JRA4 meeting 17 GN2 starting position against NLR l Weak: GN2 are late and has one low budget for production network and research l Strong: –More advanced transmission technology? –More Fibre miles than NLR ? –Ability to further replace leased services by dark fibre lines each year? –Transition of NRENs and academic MANs to dark fibres with GN2 support? –DF testbed for GN2 upgrade preparation?
