  1. CEF Networks lighting Stanislav Sima October 18th, 2004

  2. National LambdaRail in USA • The first National LambdaRail link was litin 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 University of Essex meeting

  3. 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 University of Essex meeting

  4. NLR Topology University 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. • Internet2 has established the National Research and Education Fiber Company (FiberCo) to help these groups acquire regional fiber. University of Essex meeting

  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 …. University of Essex meeting

  7. 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? University of Essex meeting

  8. University of Essex meeting

  9. 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,…. ) University of Essex meeting

  10. University of Essex meeting

  11. SANET transmission devices • Leased dark fibre G.652 • Length of backbone 860 km • Total lenght 1220 km • Catalyst 6509 at POPs • Catalyst 3524 as a signal amplifier • Backbone speed 1 Gbps University of Essex meeting

  12. Installed fiber PIONIER nodes Fibers+pipes started in 2003 Fibers+pipes planned in 2004/2005 PIONIER nodes planned in 2004/2005 Pionier fibre network University of Essex meeting

  13. Pionier transmissiondevices • Owned dark fibres G.652, G.655 • 10 Gigabit Ethernet Black Diamond 6808 switches • ADVA FSP 3000 Slimline as regenerators • 21 nodes University of Essex meeting

  14. AMREJ - Serbia University of Essex meeting

  15. AMREJ transmissiondevices • Leased lines G.652 • Inter-city fiber length 1 400 km • Catalyst 6509 and 3550 • SEEFIRE: IST3 project proposal for CEF networks deployment in SEE countries University of Essex meeting

  19. 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 University of Essex meeting

  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 University of Essex meeting

  21. Low cost technology deployment Long NIL (span > 150 km) Pure optical long multi span (span > 150 km) OEO regeneration on PIC Single colour Initially deployed Important now ? Multi colour Initially deployed Important now ? Low costs transmission technology for CEF networks University of Essex meeting

  22. Acknowledgement • Lada Altmanova for dark fibre acquiring • Miroslav Karasek and Jan Radil for lighting of CESNET2 and CzechLight fibres • Comment: presented ideas and opinions are result of our ongoing R&D activities and are opened to improvement University of Essex meeting
