A PCIe switch stores therein a first identifier used by a CPU to identify a device, a second identifier that is a common identifier to identify the device in a network formed among a plurality of switches that connect the CPU to the device, and a destination of an access request to the device in an associated manner. When having received an access request from the CPU, the PCIe switch identifies a second identifier and a destination that are associated with a first identifier included in the access request. After that, the PCIe switch adds the identified second identifier to the access request, and transmits the access request with the second identifier added to the identified destination.
