  1. Delivering Advanced Connectivity toIreland’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

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

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

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