HEAnet and its steps into fibre land
Workshop on Customer Empowered Fibre Networks
Prague, May 25th, 2004Victor Reijs
Outline
Investigating ÁRDnet services... Fibre availability... Outsourcing or not?…
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
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…
Outline
Investigating ÁRDnet services... Fibre availability... Outsourcing or not?…
National fibre
Dublin
1300 km
Fibre on overhead power lines
Regional MANs
Dublin~ 130 km
Galway~ 80 km
Limerick~ 80 km
Cork~ 80 km
Galway MAN fibre
Survey of Dublin fibre
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
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
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
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
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?
