• Project Background • Current Status – Connectivity – Service delivery • Implementation – Network build – Design – Technologies used • Pilot phase oriented
Outline
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 lambdas
Multiplexing
Different light frequencies (colours) over a single fibre path Separating lambdas Ethernet transmitters Ethernet receivers • 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)
Access Layer transmission
Backhaul Transmission (Adva)
TX/RX EDFA DCF OSC
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 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:
