Based on the analysis of the characteristics and application advantages of PLC-NET, this paper proposes three networking schemes: PLC-HLAN, PLC-VPN and PLC-AN. At the same time, the hardware composition of the bus home network is given, and the application of the CSMA / CD and the application layer CAL of the MAC sublayer of the network is analyzed. In the application of multiple PLC-VPNs, the automatic meter reading system is taken as an example , The concrete realization of its networking is given, including the structure of data nodes, concentrators and routers in the network; the structure of PLC-AN and the convergence of triple play in the business integration of PLC-NET, telecom network and computer network are given Access methods, including transmission technology quality assurance system and the corresponding application protocol
