Outline
• Project Background
• Current Status
– Connectivity
– Service delivery
• Implementation
– Network build
– Design
– Technologies used
• Pilot phase oriented
Some Background:
• Initial ITnet Services Scoping task
• Decision to commence as a “pilot” project
• 3 pilot sites chosen:
– Waterford IT
– Limerick IT
– Blanchardstown IT
• 3 primary services chosen:
– General IP transit
– Connectivity to An Cheim
– Commodity IP transit

Current Status (Connectivity)
• Dark fibre connections to WIT, LIT, ITB currently in production
• Dark fibre connections to LYIT, Sligo IT, DKIT GMIT, Cork IT and An Cheim
now complete
• Circuit rollout for remaining sites currently underway (RFT process)
• Backbone regional PoP installed in WIT
• Backbone regional PoP scheduled for install in DKIT next week
• Further dark fibre quotations to eGov are being evaluated (Commodity IP)
Current Status (Services)
• General IP transit for ITB, WIT, LIT has been
migrated (each at 260Mbps)
• Technical solution for An Cheim fully tested; now
awaiting approval for cutover
– Now a total of 3 service providers
– Failover scenarios simulated in lab
• Some outstanding negotiations still required
regarding Commodity IP transit link
Implementation
• Use of regional Government MANs reached
via NBE (dark fibre)
• Network design in access network (last mile)
• Use of CWDM for multiple wavelengths
• New Points of Presence
• Equipment used on NBE & regional network
Access Network
(Government MANs)
• Previously, regional dark fibre was a scarcity

mux/demux
It is planned to eventually provide a resilient connection to both Carriganore & College St. by forming
a MAN ring. In the interim, coloured wavelengths will be used on both point-to-points in anticipation
of this future work.

Waterford Core Ring
Blanchardstown IT
• Dark fibre point-to-point circuit to DCU PoP
– Complimented by existing 10Mbps circuit
• Substantial civil works complete at DCU after
lengthy delays
• General IP connectivity finally migrated on
26/10/06
Services Implementation
• Initial services migration:
– Connectivity to An Cheim
– General Internet connectivity
– Commodity IP transit

E-Gov Services/Commodity IP
Transit
• Progress to date has been slow
• Requires circuit to the e-Gov interconnect at 40-50 Citywest
• Negotiations with eGov regarding most suitable interconnect
point are ongoing
– One possibility is INEX at DEG, and/or Telecity
• Not just required for commodity IP, but also for rollout of e-Gov
services
An Cheim
•
Resilient dark fibre ring between HP hosting centre and HEAnet’s Citywest PoP is
complete
•
Colocation contract signed with HP for 1 cabinet
•
Equipment and cabinet are installed
•
Cross connect to An Cheim row is in place
•
Layer 1,2,3 design & testing phase complete
•
Implementation restricted to11pm on Friday nights!
•
Hope to shortly begin actual cutovers
General IP Migration (LIT)
• On 19/07/06 LIT’s IP connectivity was migrated to
transit HEAnet directly
General IP Migration (WIT)
• On 27/07/06 WIT’s IP connectivity migrated to transit
HEAnet network directly:
