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： Upstream network interfaces (2-1-2-N) and downstream network interfaces (5-1-5-M) have an upstream PCI-PCI bridge function and a downstream PCI-PCI bridge function, respectively. These network interfaces (2-1-2-N, 5-1-5-M) and a network (3) are incorporated in a system as a single multi-root PCI express switch. The network (3) tunnels TLPs (Transaction Layer Packets) between the upstream network interfaces (2-1-2-N) and the downstream network interfaces (5-1-5-M) or between the downstream network interfaces (5-1-5-M). This enables to distribute and connect a plurality of computers and a plurality of I/Os on a large scale without changing software, root complexes, and I/Os.

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： In a network system in which a switch forwarding packets and a control server determining route information are separated, it is desired to achieve a redundancy of the control channel by an out-of-band control channel and an in-band control channel, when the switch receives a control message regarding the flow entry registration and the like based on the route information from the control server. Specifically, the separated switch and control server are connected by a control channel for sending and receiving the control message. The switch is not only connected to a control server via an out-of-band control channel by a route dedicated to the control message, but also connected to another control server via an in-band control channel by a route which is common with a normal data communication for determining the route information, to achieve a redundancy of the control channel.

摘要： In a switching node, a low-load and high-speed control is performed without using a CPU and a network protocol, such as TCP/IP, which have been conventionally used for control from a remote control server, to realize a high-end and high-speed network service by making use of the high-speed CPU processing capacity of a remote control server. Specifically, a forwarding engine incorporates a PCI express, a PCI express LAN conversion bridge and a circuit which can access to a local bus control interface from the PCI express on the switching node. The external control server incorporates an extended network service interface driver for managing a plurality of switching nodes.
