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…

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?
