GN2 JRA4 meeting 2

CESNET Research Department Introduction to technology testing www.ces.net

Goals of GN2-JRA4(Technology and Service Testing)

Promote synergy between research activities performed by individual NRENs and research groups

Interconnect the GN2 test facility with NREN testbeds

Perform joint technology testing Provide effective feedback to the GN2 development

process Support preparation of the successor network to

GN2


GN2 JRA4 meeting 3


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 testing

technology relevant to GN2 Enhanced with technology that reflects the likely

evolution of GN2 and NGN Testbed will be strongly influenced by the findings of

the Work Item 2 Interconnecting the NREN local testbeds or NRENs Provisioning of optical connectivity infrastructure

where this is possible and economically feasible


GN2 JRA4 meeting 4


Goals of GN2-JRA4 Work-Item 2(Technology testing)

Promote synergy in technology testing between research activities performed by individual NRENs and research groups

Interconnect the GN2 test facility with NREN testbeds by dark fibres, if suitable for long distance transmission technology testing

Perform joint technology testing Provide effective feedback about technology to

the GN2 development process Support preparation of the successor network

to GN2


GN2 JRA4 meeting 5


WI2 goals cont. To bring related European network

research activities together and continue them on a pan-European level

Increasing the testbed range to a pan-European dimension

Each participating NREN will participate in technology testing according to its expertise


GN2 JRA4 meeting 6


WI2 goal: to gain experience with emerging networking concepts not currently used in

production research networks.

Examples given in GN2 TA include: Dark fibre provisioning and operations Long Haul and Ultra Long Haul

transmission over dark fibre Multi-colour (multi-lambda) transmission Passive optical transmission All-optical networking Generic Frame Procedure (GFP) Other advanced networking technology

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 11


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 12


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.

Cisco (Pirelli) 15808 transmission equipment, 4x10Gbps, expandable


GN2 JRA4 meeting 13


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 14


NLR Topology


GN2 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.

Internet2 has established the National Research and Education Fiber Company (FiberCo) to help these groups acquire regional fiber.


GN2 JRA4 meeting 16


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 17


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 18



GN2 JRA4 meeting 19


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 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 23


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 24


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:1. DF offers for research support2. Special possibilities that will result from

GN2 procurement3. Support of interested NRENs over 50%

cost sharing


GN2 JRA4 meeting 25


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 26


Steps to continent-wide DF testbed(if JRA4-WI2 relevant partners will be interesting)

Poznan-Prague: 2Q 2005 Prague-Budapest: 4Q 2005 London-Prague: 2Q 2006 Prague-Milano: 4Q 2006 Milano-Madrid: 2Q 2007 Budapest-Bucharest: 4Q 2007 Bucharest-Athena: 2Q 2008? To start negotiation about costs?
