Summary:A statistical-information generating unit (21) monitors packet data output from a transaction layer that constitutes architecture of a PCI Express. The result of the monitored is feedback-controlled to a weight-information updating unit (22) in real time, and is reflected in an arbitration table (14). A priority is set to the packet data corresponding to a quantity of the packet data actually transferred on a serial communication path.
