ITU-T specifies VoIP latency standards. Per discussion on 1/17/2008 with Dennis Holstein (considered US Expert to several international standards bodies), IEEE Std 1646-2004 is the latest published work on power communication performance. However, as the IUN matures, these requirements could change.
Network Issues – Home Example Order of magnitude – Tens of millions – Externally driven by customer choice Ownership – Private or utility – Design, maintenance, troubleshooting, records Types of devices – Thermostat, pool pump, water heater, lights… Network technologies – Wired – Category 1, 3, 4, 5, 6, 7… – Wireless - paging, cellular, WiMAX, RF-mesh, WiFi, ZigBee, 6LoWPAN… – Electrical – X.10, PLC, HomePlug 1.0, HomePlug AV… Addressing responsibilities – Link, network, public or private Protocol support – IPvX?... Security – Joining the network, profiles, protecting the home, protecting the utility, encryption Gateway – Meter, DSL, cablemodem, WiMAX Control – Data standard, local control, utility control, state, upgrades Public Private PSTN Internet Vendor Mobile Emergency Ext Grid Op R R R S S S S C A M A A A A A A A A A A A A A A A A A A A A M M M M M R R HomeNeighborhood Access Backhaul Core ExtraNet R R SC C M S S S Neighborhood Area Network Access Network Backhaul Network Core Network Similarly for these networks
