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

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

      • 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. Price ranges dedicated fiber infra In Euro/meter € 0 € 10 € 20 € 30 € 40 € 50 € 60 rural urban 48 4 24 96 strands
    • 24. New ways for the network to fail…
    • 25. Thank you. Questions? Further reading: http://www.surfnet.nl/ http:// www.gigaport.nl/ Speaker’s e-mail address: [email_address]
