ATUG Roundtable – November 2009 NBN Architecture Reference Model
NBN Project ATUG Round-table Nov 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
NBN Project ATUG Round-table Nov FTTx – Variations of a common theme
NBN Project ATUG Round-table Nov Seven NBN related topics August - Initial work started on 3 topics September – Additional 2 topics startedOctober – Remaining 2 topics started NBN Project Structure
NBN Project ATUG Round-table Nov Draft only – Work In Progress Group: Reference Architecture NBN Reference Model
NBN Project ATUG Round-table Nov 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
NBN Project ATUG Round-table Nov FTTH reference architecture Draft only – Work In Progress Group: Reference Architecture
NBN Project ATUG Round-table Nov Not just about speed Latency Traffic Shaping QoS queuing Encryption IPv6 Data, Voice, Video Group: Wholesale Services
NBN Project ATUG Round-table Nov 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
NBN Project ATUG Round-table Nov 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
NBN Project ATUG Round-table Nov Construction Standards – “Greenfields” Conduit, “pit and pipe” Connectors, Splicing, Optical Budget Developer and Approval authority checklists Group: Early Stage Deployments
NBN Project ATUG Round-table Nov International Standards Ensuring the Australian architecture corresponds with international precedents and standards Group: Technical
NBN Project ATUG Round-table Nov 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
NBN Project ATUG Round-table Nov Transition How will we migrate from here to there? Group: End User Migration
NBN Project ATUG Round-table Nov 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?
NBN Project ATUG Round-table Nov 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
NBN Project ATUG Round-table Nov NBN Reference Model FTTP Options for Points of Interconnect Group: Reference Architecture
NBN Project ATUG Round-table Nov Layered Relationships
NBN Project ATUG Round-table Nov Sustainability Robustness Security IPv6 Future Proofness Further Considerations Every NBN Project document must consider –
NBN Project ATUG Round-table Nov ONT – the NBN boundary…. Probably Multi-port POTS, Data, Video?
NBN Project ATUG Round-table Nov More ONTs Note – 4 ethernet ports, no POTS/Video on this one – enables gateways inside the house
NBN Project ATUG Round-table Nov Multiple Services > Multiple CPE FTTH Council AsiaPacific
NBN Project ATUG Round-table Nov A glimpse of the future
NBN Project ATUG Round-table Nov Multiple Services > Multiple CPE Future NBN- connected wiring cupboard?
