Abstract
Whether the node to which data has been sent is connected to a bus is determined according to destination information, and, when it is determined that the node is not connected to the bus, predetermined error information is sent to the data transmission source. Therefore, data re-transmission is prevented and thereby the frequency band of a network is efficiently used.
