Embodiment Construction

[0039] A network device according to a preferred embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

[0040] FIG. 1 is a structural view showing a home network system to which a network device according to the present invention is applied.

[0041] Referring to FIG. 1 , a home network system 1 accesses a service server 3 via the Internet 2 , and a client device 4 accesses the service server 3 via the Internet 2 . That is, the home network system 1 is connected to the service server 3 and / or the client device 4 to perform communication.

[0042] A network outside the home network system 1 , such as the Internet 2 , includes additional constituent elements according to the type of the client device 4 . For example, when the client device 4 is a computer, the Internet 2 includes a Web server (not shown), and when the client device 4 is a portable terminal or a mobile communication terminal, the Internet 2 includes a W...

Abstract

The present invention discloses a network device which can access a home network system and perform network communication based on a predetermined protocol, by using a minimum number of resources of an embedded microcontroller. The network device communicates with at least one electric device through a network. The network device adopts a protocol consisting of an application layer for processing a message for controlling or monitoring the electric device, a network layer for performing network connection to the electric device, a data link layer for accessing a shared transmission medium, and a physical layer for providing a physical interface with the electric device. The application layer further includes an application sublayer for performing a network management function or managing device information.

Description

technical field [0001] The present invention relates to a network device, and more particularly, to a network device capable of accessing a home network system and performing network communication based on a predetermined protocol using a minimum number of resources of an embedded microcontroller. Background technique [0002] The home network connects a variety of digital home appliances, whereby users can always enjoy convenient, safe and economical living services at home or outdoors. With the development of digital signal processing technology, refrigerators or washing machines, which are called white household appliances, have been gradually digitized, household appliance operating system technology and high-speed multimedia communication technology have been intensively applied to digital household appliances, and new Information appliances for improving home networks. [0003] As shown in Table 1, home networks are classified into data networks, entertainment network...
