• 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-GE-lambda + overprovisioning + KIS

Why Lambda Services?Why Lambda Services?Why Lambda Services?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

• 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

• 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 ServicesSURFnet6’s IP ServicesSURFnet6’s IP ServicesSURFnet6’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

• 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?So, what are Light Paths?So, what are Light Paths?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

• Many data collection points

• Processing in Groningen

• Large data sets distributed to many destinations in The Netherlands and abroad

Users: Three categoriesUsers: Three categoriesUsers: Three categoriesUsers: 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, virtual-presence

– Need very fat pipes, limited multiple Virtual Organizations, few to few
