摘要： A switch (304) includes a plurality of bridges (3041, 3042, 3043, 3044, 3045) and a switch forwarding mechanism (20). Each of the bridges transmits and receives a TLP frame complying with PCI express to and from a device connected to each of the bridges. The switch forwarding mechanism includes a plurality of ports (1, 2, 3, 4, 5) to which the bridges are connected, respectively, selects an output port in dependence on a combination of destination information on the TLP frame input from one of the plurality of ports and the port which input the TLP frame, and outputs the TLP frame from the selected output port.

摘要： A packet communication device autonomously selects an appropriate operation mode according to a connection environment to an external device before a service of the device is started. When the device is connected to the external buses, connection interface units notify an external device discrimination unit of connection of the device. The external device discrimination unit issues a polling packet to the connected device, discriminates the connected external device on the basis of the response packet, and notifies an operation mode switching unit. The operation mode switching unit selects an operation mode conforming to a connection environment of the packet communication device to the external device and switches the operation mode of the device to the mode. The selection of the operation modes is completed before the entire device or a portion of the device which is influenced by the selection of the operation mode starts a service to the external device to which the packet communication device is connected.
