HOME NETWORK SYSTEM, ESPECIALLY CONCERNED WITH APPLYING A LIVING NETWORK CONTROL PROTOCOL, AND TRANSMITTING/RECEIVING AND PROCESSING A RECEIVED PACKET ACCORDING TO THE NETWORK LAYER PACKET TYPE OF THE RECEIVED PACKET

摘要

PURPOSE: A home network system is provided to apply an LnCP(Living network Control Protocol) in order to offer a function of controlling and monitoring home appliances and to transmit/receive and process packets by using a home code for network security. CONSTITUTION: A layer structure(200a) for LnCP access units comprises two physical layers(90a,90b) so as to be connected with networks formed with different transmission mediums(for example, a serial interface and a power line). The layer structure(200a) also comprises data link layers(80a,80b) corresponding to each of the physical layers(90a,90b). The layer structure(200a) also comprises a network layer(70) to connect between the data link layers(80a,80b). The layer structure(200a) additionally comprises a home code control auxiliary layer(71a) that manages a home code for network security. The home code control auxiliary layer(71a) is formed between the data link layer(80b), connected to a power line, and the network layer(70).
