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

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)

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:
