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： A VPN connection method and a communication system are provided, each which can omit the setting of a firewall and the installation of a relay server and can establish communications from the outside of a firewall to the inside thereof. The internal network 2 is connected to the external network 1 via the firewall 13. The internal network 2 enables communications by an e-mail from the external network 1 (outside the firewall) to the mail server 21 in the internal network 2 (inside the firewall) or communications by telephone or radio, which is not via the firewall 3. The feature of the firewall 3 is utilized that access from the outside to the inside of the firewall through VPN connection is very difficult but the access in the reverse stream can be simply performed. Using the mail server, telephone line or radio line, the internal network 2 receives an e-mail, which requires for VPN connection from the external network 1, or control information through the telephone line. Thus, the internal network 2 sends callback for VPN connection to the e-mail transmission source. As a result, the callback allows the external network 1 to pass through the firewall 3.
