SURFnet5
• Partners BT and Cisco
• 15 PoPs connected by
thirty 10 Gbit/s lambdas
• Dual stack IPv4 and
IPv6 since 2001
• 500,000 users
• 60% customers
connected at Gbit/s
level
6
What did we learn
• Lambdas are an excellent basis for IP networking
• Dark fiber and gigabit Ethernet is an excellent way to
connect customers
• Researchers are interested in direct access to
lambda’s for high bandwidth, low jitter, low latency
point tot point connections
• Incumbent operators were reluctant to sell dark fiber
• Added value of network operators in NG NRENs is
limited
• International cooperation in developing lambda
networking is essential
7
NREN challenge
• Accommodate needs of scientific users for
higher speed, higher quality networking
• While protecting the performance of the
network for current users
• And keeping the successful end-to-end model
of the internet

What did we learn
• Point to point lambdas is a powerful service
• Current Optical-Electrical-Optical equipment
is capable of allocating sub-lambdas to
individual applications
• Management is still cumbersome
• Hybrid network architecture seems to be
the only valuable NREN option for the
future:
– Packet switched internet for regular
many-to-many usage
– Light path switched internet for new high
speed few-to-few usage
• LambdaGRID is needed
16
LambdaGrid
• A grid is a set of networked, middlewareenabled computing resources.
• A LambdaGrid is a grid in which the lambda
networks themselves are resources that can
be scheduled, like all other computing
resources.
17
TransLight
• Emerging Global-Scale LambdaGrid for e-Science
• Hub and spoke model, initially around StarLight
and NetherLight
• Will not replace current best efforts networks
• Major initial funding
– GigaPort Project (SURFnet)
– US National Science Foundation (Euro-Link award
to University of Illinois at Chicago)
– Canada's CANARIE
• “bring us your lambdas”

Design principles GigaPort NG
Network
• Realization of a next generation network with
seamless end-to-end communication:
– Integration of lambdas in the IP network
– Multi-domain networking
– Ethernet services as part of the WANs
– Intelligence of networks and the associated
responsibilities at the edges
• Paving the way to a ubiquitous and scalable
Services Grid
23
SURFnet6 overview
• Congestion free transparent end-to-end IP
transport
–unicast and multicast; IPv4 and IPv6; all at
wire speed
–1 Gbit/s, 10 Gbit/s and beyond
• Lambda services to eventually all connected
organizations
• Layer 1: DWDM equipment
• Layer 2: Ethernet equipment
• Layer 3: Small routed core at 2 to 5 locations
24
SURFnet6 will be based
on Dark Fiber
• Over 3000 km fiber pairs
already available, average
price paid for 15 year IRUs
is 7 Euro/m per pair.
• More than 25 co-location
facilities in use.
• Managed dark fiber
infrastructure will be
extended with new routes
25
SURFnet6 Call for Proposal for
industrial partner(s)
• In June 2003 a Contract Notice has been
published in the Official Journal of the EC to
invite industrial partners to contribute to the
final design of SURFnet6 and take
responsibility for supplying, implementing,
maintaining and supporting transmission,
switching and routing equipment for
SURFnet6
26
Timelines SURFnet6
27
Conclusion
• NREN users need new services that current
networks will not be able to support
• Telecommunication infrastructures will
become part of the grid and will be
intergrated in scientific instruments
• NRENs do need to react carefully and timely
to these developments.
• Lambda networking is not a revolution
