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

Wavelength Division Multiplexing
• CWDM in access network (1470nm – 1610nm. 8 x channels, modulated at 1Gbit/s)
• DWDM in backbone. Each channel capable of 10Gbit/s (1 channel initially)

Points of Presence
• Regional Layer 2 & Layer 3 PoP located in room A0-060 Main Building University of Limerick
• Disaster recovery PoP located in Library comms room (@ intersection of access & core ring)
• CPE located in LIT comms room 1A.05– Patched through adjacent room 1A.06
• Backbone transmission PoPs located in ESBT substations, at Killonan and Drumline

Waterford Regional λ Planning 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.

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:
