摘要： A network system that is part of a main system includes: a first PCI express-network bridge with a first control unit and a first PCI express adapter terminating a first PCI express bus; and a second PCI express-network bridge connected to the first PCI express-network bridge through a network. The second PCI express-network bridge includes a second control unit and a second PCI express adapter terminating a second PCI express bus, wherein the first control unit detects a destination of a packet sent from the first PCI express adapter, searches a physical address of the destination from a packet encapsulating table, and encapsulates the packet in a frame so that the frame includes the physical address, and wherein the second control unit removes the encapsulation tagged to the packet, and transfers the packet to the destination through the second PCI express bus by referring to a PCI express configuration register.

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.

摘要： A PCI Express switch which connects a plurality of peripheral devices to an arbitrary one of a plurality of CPUs through an Ethernet is constituted by a plurality of upstream and downstream PCI Express-network bridges, an Ethernet switch, and a system manager. Each of the upstream and downstream PCI Express-network bridges includes a PCI Express adapter which terminates a link of a PCI Express bus, a network adapter which terminates a link to the Ethernet switch, and a control unit which encapsulates a TLP in a frame, the destination of which is a MAC address of a bridge to which the destination is connected to transmit and receive the frame. Because the switch according to the present invention comprising a plurality of upstream PCI Express-network bridges and a plurality of downstream PCI Express-network bridges connected to the plurality of upstream PCI Express network bridges through a network is equivalent to a conventional PCI Express switch, it is needless to change a conventional PCI software.

摘要： Any packet loss is detected very quickly by means of only a series of sequence number in a multi-path environment where a transmitter and a receiver are connected to each other by way of a plurality of networks when no inversion of sequence arises in any of the networks. A communication apparatus includes a plurality of sequence buffers arranged at each network to accumulate packets until a sequence acknowledgement and an absence detecting section adapted to determine the occurrence of an absence of a packet when one or more packets are accumulated in all the sequence buffers. With this arrangement, the absence detecting section of the receiver monitors the packets staying in the sequence guaranteeing buffer arranged in each of the network, paying attention to the characteristic that packets are stored in the sequence buffers of all the networks when a packet loss takes place.
