Abstract: A virtual tunnel endpoint that makes a communication of a specific tenant is separated from virtual tunnel endpoints that make communications of the other tenants. A forwarding route from the virtual tunnel endpoint that makes a communication of the specific tenant is separated from a forwarding route from the virtual tunnel endpoints that make communications of the other tenants. Accordingly, a communication of the specific tenant is forwarded with priority.

Abstract: A system manager sets a port connected to a specific device (for example, a router device) among a plurality of ports of a switch device as a reliable port. If a packet is received in the reliable port, the switch device manages an IP address and a MAC address of the router device by a reliable port information table. When a packet is received from a port not set as the reliable port, the switch device refers to the reliable port information table. At this time, when the received packet is an address resolution packet having impersonated a router device, the switch device discards the packet without transmitting the packet, thereby preventing a cyber attack on a terminal.

Abstract: A simple configuration for cooling comprises a front-back air supply and exhaust system. A first circuit board is located in front of a relay circuit board. A cooling unit and a second circuit board are placed behind the relay circuit board in a chassis. A first air passage allows intake air through an intake hole in a front side of the first circuit board unit to pass through the first circuit board and then through an opening in the relay circuit board to the cooling unit. A second air passage allows intake air through an intake hole in a front face of the chassis to pass through a lateral side of the first circuit board and then through a vent hole in a partition provided at the lateral side of the first circuit board. The second circuit board is placed in the second air passage.
