Abstract
The present invention eliminates the shortage of bus numbers in routing control using PCIe switches. A system port address (SPA) is associated with a destination bus number and is assigned to a port (external port) connected to a server and a device. When packets sent from the server or the device are received at the external port, the system port address (SPA) corresponding to the destination bus number having the packets is determined, and the SPA is added to the packets as a label. This SPA is used to route the packets sent between ports (internal ports) that connect switches. When the packets arrive at the external port to which the target server or device is connected, the destination bus number having packets is used to send the packets to the server or device connected to the external port.
