A relay apparatus according to an embodiment of this invention includes an ID acquisition unit configured to acquire the unique ID of a partner device connected to a predetermined network, and a control unit which controls various processes on the basis of the unique ID of the partner device, which is acquired by the ID acquisition unit.

Relay apparatus and network relay method

Node c, which is connected by two different protocols, that is, the IEEE 1394 as a line transmission system and the radio transmission system, becomes the bus manager through bus arbitration, and allocates ID to each of nodes a to d in the network. In data transmission, the transmission rate informing part in node c informs each of nodes a to c of the maximum rate in the radio transmission system. The communication procedure converting part and the signaling type converting part in node c convert into the communication procedure and the signaling type suitable for the radio transmission system, and transmit the converted data to node d in the radio network through a communicating part for transmission system B, thereby enabling real time data transmission.

Method and apparatus for connecting network

A contact apparatus for a network in which a plurality of outlets are connected with each other by a repeater through a bus. A cable contains a bus to transmit signals and a power supply line. When the cable is connected with one of the outlets, the device concerned participates in the network and the power supply voltage is supplied to the device. Data can be exchanged between the devices only by connecting the cable with the outlets.
