GigaPort/SURFnet5 conclusions
• SURFnet5 is still world leading network, but…
– NREN users need new services that current networks
cannot support
– Data communication infrastructures will become part of the
Grid and will be integrated in scientific instruments
– Hybrid networks delivering IP and Lambda Services can
meet user demand within budget constraints, using IP-GElambda + overprovisioning + KIS
Why Lambda Services?
• Provides excellent quality on point to point
connections at very high speed
• Protects the routed network
• Enables demanding applications to make use of the
infrastructure in an economically sound way
SURFnet’s new Industry Partners (2004-2010)
• Optical equipment
• Ethernet equipment
• Network management
equipment
• Routing equipment
• Installation services
• Maintenance services
SURFnet6 will be based on dark fiber
• Over 4000 km fiber pairs
available today; average
price paid for 15 year IRUs:
7 EUR/meter per pair
• Managed dark fiber
infrastructure will be
extended with new routes,
approx. 1000 km more to
be ready for SURFnet6

SURFnet6 overview
• Realization of a next generation hybrid network with
seamless end-to-end communication:
– Based on customer-owned managed dark fiber
– IP Services and Lambda Services over a single transmission
infrastructure managed, via a single control plane
– 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
SURFnet6’s IP Services
• IPv4 and IPv6 connectivity:
– Unicast
– Multicast
• Small routed core in Amsterdam at two distinct
locations
• Congestion-free (lambda services aid to this!)
• Resilient
SURFnet6’s Lambda Services
• Lambda Services: Light Path provisioning
• Enables users or applications to make, or signal for,
service level changes to their layer 2 paths
• Characteristics:
– Flexible
– Economical
– Reliable
– High-speed, i.e. 1G or 10G
• Light Paths aren’t constrained by traditional
framing, routing, and transport
So, what are Light Paths?
• A Light Path has the following characteristics:
– No packet re-ordering
– No jitter
– No drops due to congestion
– Known end points
• A Light Path can therefore:
– Bypass firewalls between trusted parties
– Enable the use of alternate network or transport protocols

LOFAR
• Many data collection points
• Processing in Groningen
• Large data sets distributed to
many destinations in The
Netherlands and abroad
Users: Three categories
• Lightweight users doing browsing, mailing, home use
– Need full Internet routing, one to many
• Business applications, multicast, streaming
– Need VPN services and full Internet routing, several to several
• Special scientific applications, computing, data grids, virtualpresence
– Need very fat pipes, limited multiple Virtual Organizations, few to few
