Outline

Outline

  • Investigating ÁRDnet services...

  • Fibre availability...

  • Outsourcing or not?…


Investigated rdnet services

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)


Service provisioning

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…

Selecting a fibre provider

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


Some challenges

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


Possible fibre topology

Possible fibre topology


Some fibre experience

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.

Essential work by heanet

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


Possible outsourcing

Possible outsourcing

  • Operational management

    • e2e fibre

    • layer 1+2

  • Specification of RfI:

    • FLEXIBILITY

    • ability to listen to HEAnet
