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 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
