Abstract: A packet processing device is connected as a route of a plurality of I/O devices and configures a PCIe fabric. The packet processing device includes a plurality of first request processing units and a second request processing unit that process a PCIe packet issuing request to the I/O device; and a first selecting unit that selects the plurality of first request processing units or the second request processing unit, based on a request classification of the PCIe packet issuing request, and a load exerted on the PCIe fabric by a packet to be transmitted to the I/O device. The first selecting unit includes a first determining unit that determines whether the PCIe packet issuing request is possible to pass another PCIe packet issuing request being processed by the first request processing unit, based on a transaction identifier included in the PCIe packet issuing request.
