  1. Managed Dark Fiber @SURFnet Erik-Jan Bos Director of Network Services SURFnet TERENA workshop on NREN-controlled fibers København, Danmark – October 24th, 2003

  2. Contents • SURFnet and GigaPort • SURFnet5 infra: lambdas and fibers • GigaPort NG Network infra: fibers only • Lessons learned

  3. Contents • SURFnet and GigaPort • SURFnet5 infra: lambdas and fibers • GigaPort NG Network infra: fibers only • Lessons learned

  4. GigaPort results • Realization exceeds plans within budget • SURFnet5 10 Gbit/s based network up&running • Native support of IPv4 and IPv6 • Multicast support based on PIM-SM • 60% of customers connected via Gigabit Ethernet • 20,000 students via 10/100 Mbit/s Ethernet • Congestion free global Internet connectivity • NetherLight: major hub internat. lambda network • Development of market for managed dark fiber • Partnership contribution higher than estimated

  5. SURFnet network generations • SURFnet1: DECnet Phase 4 over public X.25 • SURFnet2: DECnet and IP over private X.25 • SURFnet3: IP and X.25 over leased lines • SURFnet4: IP over ATM over SDH over glas/koper -> IP over SDH over glas • SURFnet5: IP over DWDM/glas • Moving towards simpler architectures (KIS)…

  6. Contents • SURFnet and GigaPort • SURFnet5 infra: lambdas and fibers • GigaPort NG Network infra: fibers only • Lessons learned

  7. SURFnet5 topology

  8. SURFnet5: lambdas and fibers • 15 large PoPs • thirty 10G lambdas • Resilience on IP level! • 150 institutes • 102 institutes connected at Gbit/s level (HSDrenthe = #100)

  9. SURFnet5 topologie Deventer Arnhem GE

  10. GigaMAN concept: ring structure • Ring starts and ends at existing SURFnet PoP • Client locations on the ring are added like “pearls on a necklace” To Core To Core PoP Institution Institution Institution Institution

  11. FttD concept: Same duct, different pair University in house UTP 10-100 Mbit/s Dormitories One fiber pair: 1 Gbit/s in house UTP 10-100 Mbit/s SURFnet in house UTP 10-100 Mbit/s

  12. Contents • SURFnet and GigaPort • SURFnet5 infra: lambdas and fibers • GigaPort NG Network infra: fibers only • Lessons learned

  13. Paradigm shift Next generation networks cannot be a simple extrapolation of the existing networks

  14. GigaPort NG Network Bsik proposal • Consortium of 50 partners on demand / research side • SURFnet is the executive organization • Submitted in Bsik program • decisions for grants expected October 2003 • Project focuses on implementation next-generation network and includes research on networks

  15. (1) SURFnet6 overview • Congestion free transparent end-to-end IP transport as of 1 July 2005 • 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 • Additional functionality after 2005 • 150 - 200 connections • Layer 1: DWDM equipment • Layer 2: Ethernet equipment • Layer 3: Small routed core at approx. 2 locations

  16. Firm belief: All fixed infra will move to fiber

  17. Market: Unequal spread of infra Pictures: Yuri Demchenko

  18. (1) Building blocks for SURFnet6 • Managed dark fiber infrastructure (will be extended with new routes) • More than 25 co-location facilities • Operations • Upstream and peers

  19. Contents • SURFnet and GigaPort • SURFnet5 infra: lambdas and fibers • GigaPort NG Network infra: fibers only • Lessons learned

  20. Fibers @SURFnet • *Managed* dark fiber • IRU for 15 years (upfront payment and maint) • October 2003: ±3000 km managed dark fiber • In 2004: last fibers routes added to be “self-supporting fiber-wise” (e.g. Wageningen, Maastricht and Den Haag)

  21. Problem areas • Synchronization of buying power • Specific position of city councils • Law issues • Infrastructure public... or not... • Protesting operators Cook book: http://gigaman.gigaport.nl

  22. SURFnet’s advice to local/city governments • The government is expected to organize its internal matters efficiently and buy rationally • Buying power with city government leaves government in a safe “launching customer” role • No market disruption as long as the line is not crossed between “take care of your self” and “delivery to third parties” is not crossed

  23. In Euro/meter € 60 € 50 € 40 96 strands € 30 24 € 20 48 4 € 10 € 0 rural urban Price ranges dedicated fiber infra

  24. New ways for the network to fail…
