  1. HEAnet and its steps into fibre land Workshop on Customer Empowered Fibre Networks Prague, May 25th, 2004 Victor Reijs victor.reijs@heanet.ie

  2. Outline • Investigating ÁRDnet services... • Fibre availability... • Outsourcing or not?…

  3. Investigated ÁRDnet services • Physical connectivity: • ethernet framing upto 1(-10) Gbit/s • resilient paths • IPv4/IPv6/multicast (inter)national transit • Customer empowered services: • intra institute LAN connectivity (p2p) • inter institute project connectivity (p2p)

  4. Service provisioning • User stack (control plane, UCLP) • Deterministic, what does it mean? • Reordering • BER guarantees • Rate limiting issues • Non-recoverable unused capacity • fibre, WDM, SDH • Recoverable unused capacity • ethernet, IP, MPLS • FLEXIBILITY • control needed down to fibre…

  5. Outline • Investigating ÁRDnet services... • Fibre availability... • Outsourcing or not?…

  6. National fibre Dublin 1300 km

  7. Fibre on overhead power lines

  8. Regional MANs Galway ~ 80 km Dublin ~ 130 km Limerick ~ 80 km Cork ~ 80 km

  9. Galway MAN fibre

  10. Survey of Dublin fibre

  11. Selecting a fibre provider • Commercial/non-commercial/ governmental • Fibre footprint • Diverse fibre Splice flexibility • Costs • General legal issue: IRU-lease-rental VAT (21%)/stamp duty (9%)/depreciation

  12. Some challenges • Joint usage of ducting, manholes, sub-ducting • Digging last stretch • Digging can be restricted by a council • Need to use other fibre providers • Relatively unfixed civil costs • Optimise fibre use: • costs • resilience • additional PoPs

  13. Possible fibre topology

  14. Some fibre experience • NYSERnet fibre ring in New York • Lightpath testing between TWAREN and HEAnet (using ULCP olf CANARIE) • Always get an OTDR trace from between each site. Saves time and money!!! • dB budget essential for calculations • Permits/permission to carry out civil work can take very long periods of time to get. Up to 6 months. Permission can also be denied. • Contract negotiations can take 12 months from start to finish. • Plan well in advance.

  15. Outline • Investigating ÁRDnet services... • Fibre availability... • Outsourcing or not?…

  16. Essential work by HEAnet • Tactical & strategic management • Renting/owning p2p fibre • operational management outsourced. • Deciding/owning equipment • layer 1 – 3 • CfT is running • operational management layer 3 is in-house

  17. Possible outsourcing • Operational management • e2e fibre • layer 1+2 • Specification of RfI: • FLEXIBILITY • ability to listen to HEAnet • provide national service (4+4, 24*365) • utilizing HEAnet’s fibre beside other fibre • additional co-location • integration with layer-3?
