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

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

National LambdaRail in USA



The first National LambdaRail link was lit
in 2003
Last month, NLR completed the first full EastWest 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.

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

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.

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 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 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

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


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), …..

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 support
2. Special possibilities that will result
from GN2 procurement
3. Support of interested NRENs over 50%
cost sharing

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)
