1. Delivering Advanced Connectivity to Ireland’s IoTs Owen Byrne 09/11/06

2. Outline Project Background Current Status –Connectivity –Service delivery Implementation –Network build –Design –Technologies used Pilot phase oriented

3. 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

4. Integration Project Team Implementation TeamMartin McCarrick Brian Boyle Owen Byrne Project ManagerJohn Boland Steering Committee HEA DES Council of Directors IUA (CHIU) DIT Mary Kerr Ian McKenna Brendan Murphy, Tim Creedon Michael Nowlan, Brendan Tolan David Scott

5. 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)

6. 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

7. 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

8. Access Network (Government MANs) Previously, regional dark fibre was a scarcity

9. Limerick Core Ring

10. Limerick Access Ring

11. Network Design (Limerick)

12. 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) Separating lambdas Multiplexing lambdas Different light frequencies (colours) over a single fibre path Ethernet transmitters Ethernet receivers

13. Access Layer transmission

14. Backhaul Transmission (Adva)

15. 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

16. Network Design (Waterford IT)

17. New Waterford Points of Presence Layer 2 HEAnet PoP in Walton building (diverse entry points) Disaster Recovery PoP at ABT building within nearby IDA park Layer 1 backbone transmission PoP in ESBT Killoteran

18. Fibre Topology Waterford IT

19. Waterford Core Ring

20. 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

21. Services Implementation Initial services migration: –Connectivity to An Cheim –General Internet connectivity –Commodity IP transit

22. Pilot Services (L2/L3 Design)

23. 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

24. 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

25. An Cheim (BGP schema) Collaboration withEircom/Lancomms to implement an integrated failover technique across 3 Service Providers

26. General IP Migration (LIT) On 19/07/06 LIT’s IP connectivity was migrated to transit HEAnet directly

27. General IP Migration (WIT) On 27/07/06 WIT’s IP connectivity migrated to transit HEAnet network directly:
