Abstract:
1. An input/output connection device connecting a CPU and at least one input/output device, the CPU transmitting a first packet with a first tag, the input/output connection device comprising: a generating section configured to generate a second packet with a second tag; a transmitting section configured to transmit the first packet transmitted from the CPU and the second packet to the at least one input/output device, the transmitting section determining whether or not the first tag added to the first packet has a same value as the second tag added to the second packet, the transmitting section transmitting the first packet to the at least one input/output device when the first tag and the second tag have different values, the transmitting section not transmitting the first packet to the at least one input/output device when the first tag has the same value as the second tag; a receiving section configured to receive a third packet with a third tag and a fourth packet with a fourth tag from the at least one input/output device as response packets to the first packet and the second packet, respectively; a first determining section configured to determine the third packet and the fourth packet, based on the third tag and the fourth tag; and a second determining section configured to analyze the fourth packet so as to detect a failure of the at least one input/output device.
