1. ATUG Roundtable – November 2009 NBN Architecture Reference Model

2. NBN Project ATUG Round-table Nov 20092 One Network to link them all…. The NBN access network enables subscribers to access services from multiple service providers, using wholesale (?bitstream?) services. NBN Video SP Telephone SP Terminology and labels are very important

3. NBN Project ATUG Round-table Nov 20093 FTTx – Variations of a common theme

4. NBN Project ATUG Round-table Nov 20094 Seven NBN related topics  August - Initial work started on 3 topics September – Additional 2 topics startedOctober – Remaining 2 topics started NBN Project Structure

5. NBN Project ATUG Round-table Nov 20095  Draft only – Work In Progress Group: Reference Architecture NBN Reference Model

6. NBN Project ATUG Round-table Nov 20096 FTT-Home - Passive Optical Network Appears to be front-runner in NBN architecture. Unpowered optical 1:32 or 1:64 “splitter” (perhaps 1:24?) Optical Fibre ‘drop cables’ to buildings, converter-box on wall ~40km

7. NBN Project ATUG Round-table Nov 20097 FTTH reference architecture Draft only – Work In Progress Group: Reference Architecture

8. NBN Project ATUG Round-table Nov 20098 Not just about speed Latency Traffic Shaping QoS queuing Encryption IPv6 Data, Voice, Video Group: Wholesale Services

9. NBN Project ATUG Round-table Nov 20099 Service Provider Concerns Where can service providers ‘plug in’ – “5/50/500 issue”? How? Which interface standards? How can service providers innovate services? Will a subscriber be able to connect to multiple service providers simultaneously (NOT all through one ISP)? Group: Reference Architecture

10. NBN Project ATUG Round-table Nov 200910 Customer Issues – CPE access In the NGN world, the CPE and “Home Gateways” becomes vitally important Interoperability – will subscribers have choice of CPE (Pay TV Set Top Box ?) Reliability of critical services – especially when installed by the subscriber (no “LifeLine” telephone power?) Security – difficult to secure smart CPE, dumb network Group: End User Premises

11. NBN Project ATUG Round-table Nov 200911 Construction Standards – “Greenfields” Conduit, “pit and pipe” Connectors, Splicing, Optical Budget Developer and Approval authority checklists Group: Early Stage Deployments

12. NBN Project ATUG Round-table Nov 200912 International Standards Ensuring the Australian architecture corresponds with international precedents and standards Group: Technical

13. NBN Project ATUG Round-table Nov 200913 Who fixes service faults? Carrier ≠ CSP ≠ ISP ≠ TSP (VoIP?) Subscriber wants SPOC for ordering adds/moves/changes Providers want automated flow-through systems Subscriber wants one finger to point, but… Who takes responsibility to troubleshoot a problem? Who wears the TIO investigation? Group: Operational

14. NBN Project ATUG Round-table Nov 200914 Transition How will we migrate from here to there? Group: End User Migration

15. NBN Project ATUG Round-table Nov 200915 Service Transparency In the NGN world, how can multiple CPE, ASPs, ISPs, CSPs and other ‘clouds’, all with a commercial axe to grind, ‘get out of the way’ and help ensure that end-to-end services work as the subscriber wants?

16. NBN Project ATUG Round-table Nov 200916  Customer Choice “At each service delivery location, the network must enable multiple services to be active in parallel and operating simultaneously, each connected through the access network to different wholesale or retail service providers.” Draft only – Work In Progress “Each active service may be connected to different physical devices within the customer premises, and each device within the premises may distribute the service into one or more in-premises networks.” NBN Service Model

17. NBN Project ATUG Round-table Nov 200917 NBN Reference Model FTTP Options for Points of Interconnect  Group: Reference Architecture

18. NBN Project ATUG Round-table Nov 200918 Layered Relationships

19. NBN Project ATUG Round-table Nov 200919 Sustainability Robustness Security IPv6 Future Proofness Further Considerations Every NBN Project document must consider –

20. NBN Project ATUG Round-table Nov 200920 ONT – the NBN boundary…. Probably Multi-port POTS, Data, Video?

21. NBN Project ATUG Round-table Nov 200921 More ONTs Note – 4 ethernet ports, no POTS/Video on this one – enables gateways inside the house

22. NBN Project ATUG Round-table Nov 200922 Multiple Services > Multiple CPE FTTH Council AsiaPacific - 2005

23. NBN Project ATUG Round-table Nov 200923 A glimpse of the future

24. NBN Project ATUG Round-table Nov 200924 Multiple Services > Multiple CPE Future NBN- connected wiring cupboard?
