When an error is detected in a received packet, a higher application is informed that the error occurred, and when no error is detected in the received packet, the higher application is informed that the packet has been received. If a next packet is received while a packet having the detected error is stored in a data storing region, an acknowledge signal indicating that the packet cannot be received is sent to a source node, and the packet having the detected error stored in the data storing region is invalidated by a request from the higher application. When the error is detected in a received packet, that packet stored in the data storing region is invalidated.
