Dominated nodes (A,B and C) are equipped only with lower layers (1a,2a and 3a), and upper layers for the lower layers are not equipped. Each of the lower layers (1a,2a and 3a) comprises a preset device, and managing information for managing a communication function of the lower layer is read from the preset device and set to a function device of the lower layer. The dominated nodes (A,B and C) can execute isochronous transmission without a dominating node equipped with an upper layer for managing the lower layers. The dominating node is not always necessary on an IEEE1394 bus. <IMAGE>
