Stanislav Sima

Paris, November 2nd, 2004

(revised November 4th, 2004)

Selected goals of Work-Item 1(Distributed testbed in support for other activities and other FP6 projects)

Goals influenced by Work-Item 2 (Technology testing)

  • Distributed testbed to serve as a platform for testingtechnology relevant to GN2
  • Enhanced withtechnology that reflects the likely evolution of GN2 and NGN
  • Testbed will be strongly influenced by the findings of the Work Item 2

GN2 JRA4 meeting

ideas about technology testing update 2005 2007
Ideas about technology testing update (2005-2007)
  • Optical lambda switching, pure optical networking
  • Transmission and switching equipment for transmission rate 40G, 100G, 160G
  • Soliton transmission technology
  • Photonic Integrated Circuits (PIC)
  • Low cost Optical Amplification and OEO conversion
  • Others
  • Preliminary map proposals for year 2006 and 2007 before 1st November 2005

GN2 JRA4 meeting

importance of analysis
Importance of Analysis
  • Deliverables should satisfy contract on GN2 project
  • Concurrently, results should be at world leading edge (from research and deployment point of view)
  • Analysis of current and expected leading edge in new technology deployment in research networking is important: first step follows

GN2 JRA4 meeting

national lambdarail in usa
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

GN2 JRA4 meeting

crucial importance
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

GN2 JRA4 meeting

dark fibre connection of nlr users
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.

GN2 JRA4 meeting

lengths of dark fibres in rens
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 JRA4 meeting

gn2 starting position against nlr
GN2 starting position against NLR
  • Weak: GN2 are late and has one low budget for production network and research
  • 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?

GN2 JRA4 meeting

gn2 topology
GN2 topology
  • 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,…. )

gn2 testbed preparation
GN2 testbed preparation
  • Continent-wide by using GN2 lambdas
  • Partly based on dark fibres
  • Prefered connection based on JRA4 WI2 participants dealing with dark fibre lighting
  • Continent-wide dark fibre testbed needed before deployment of new technology in GN2 production network for risk decreasing

GN2 JRA4 meeting

continent wide df testbed in 2007 first proposal
Continent-wide DF testbed in 2007? (first proposal)
  • Ultra Long Hall DF testbed Line I:

Poznan – Prague – Milano – Madrid

  • Ultra Long Hall DF testbed Line II:

London - Prague – Budapest – Bucharest (-Athena)

  • DF connection to local DF testbeds: UKLight fibres (Cambridge, University of Essex), CzechLight fibres (Prague, Brno, Plzen), Pionier fibres (Poznan, Krakow), …..

GN2 JRA4 meeting

cost constraints costs are not from any tender preliminary offers are used
Cost constraints(costs are not from any tender, preliminary offers are used)
  • Such about 5000 km testbed could be too expensive (2.5 mil. Euro/year)
  • Testing of ULH technology (about 3000 – 4000 km) are important.
  • We should take into account:
    • DF offers for research support
    • Special possibilities that will result from GN2 procurement
    • Support of interested NRENs over 50% cost sharing

GN2 JRA4 meeting

preliminary status of df testbed lines
Preliminary status of DF testbed lines
  • Poznan-Prague: 413 km, available, low cost/km
  • Prague-Budapest: 535 km, available, low cost/km
  • London-Prague: 1150 km,available, high cost/km
  • Prague-Milano: 875 km, available, high cost/km
  • Milano-Madrid: 1576 km, available, high cost/km
  • Budapest-Bucharest: 796 km, available, high cost/km
  • Bucharest-Athena: 1227 km, availability not sure

(Route distances, you could use 50% more as the first apoximation of fibre lenght)

High cost: about 500 Euro/km/year (fibre pair)

GN2 JRA4 meeting
