gigaport surfnet5 conclusions
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-GE-lambda + overprovisioning + KIS
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
surfnet s new industry partners 2004 2010
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
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
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
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
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
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

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, virtual-presence
    • Need very fat pipes, limited multiple Virtual Organizations, few to few
