摘要:
In a system having two or more gateway apparatuses connected to both first and second networks having mutually different address systems, a gateway apparatus is provided with a translation table for associating IP addresses with node IDs. The gateway apparatus inquires other gateway apparatuses whether other gateway apparatuses are administering the same address as an IP address generated for a newly added device. If there is another gateway apparatus that is administering the same address, the IP address is prevented from being registered in the translation table.

An object of the present invention is to provide network devices and a network device control method which enable control network devices connected to an IP network, AV devices connected over 1394IF through gateway devices from the IP network, and home devices connected to ECHONET to be controlled without distinction among them. To achieve this object, a network device to serve as a controller comprises a controller application that detects a service of a target network device, using a message complying with an information exchange protocol common to the network, collects information such as an access method for the service, a function name, and parameters, and controls the network device upon request, and an information exchange protocol processing part that exchanges messages according to a protocol common to the network devices. The network device targeted for control comprises service that provides information for the controlling network device to perform control to the controller, and the information exchange protocol processing part.
摘要:
The present invention is intended to simplify the user's initial setup operation when connecting a new network device to a network built in his/her house/room and prevent connection of a different network device unknown to said user. A network connection management device, when receiving a network connection request from a new network device, sends the request to other network devices connected already to the network so as to be displayed on their displaying means to prompt the user to make an operation for confirming the request. The confirmation data inputted by the user through the inputting means of the network device is sent to the network connection management device, which then determines whether to permit the connection to said network. When the decision result is YES (permit), the new network device is connected to the network.
