  1. GigaPort Next Generation Network&SURFnet6 Erik Radius Manager Network Services SURFnet, The Netherlands Joint Techs Workshop Columbus, OH - July 20, 2004

  2. 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

  3. 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

  4. SURFnet’s new Industry Partners (2004-2010) • Optical equipment • Ethernet equipment • Network management equipment • Routing equipment • Installation services • Maintenance services

  5. 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 See also http://www.surfnet.nl/organisatie/netwerk/flash/kaart.html

  6. Metro fiber example (GigaMAN The Hague)

  7. 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

  8. 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

  9. 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

  10. 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
