Packet Structure and Packet Transmission Method of Network Control Protocol

Abstract

A packet structure and packet transmission method of a network control protocol. A user in the inside or outside of the house can effectively control various home appliances such as refrigerator or laundry machine or monitor operation state of the devices, over the network such as RS-485 network, low-power RF network, and power line network so that the user can enjoy the remote control and the convenient monitoring. In addition, the packet structure for the inter-layer interface in the network system can be managed. The packet structure at the network layer is generated by assigning one or more fields indicative of a packet start, a destination address, a source address, a packet length, a network layer control, an application layer protocol data unit, a cyclic redundancy check (CRC), and a packet end, and a field indicative of a network layer control. The generated packet structure of the network layer is transmitted to thus interface layers in a network system. Therefore, the packet structure at the network layer can be more efficiently managed and transmitted.
