摘要： A network relay device (10) relays data in a layer 2 network. The network relay device includes first and second communication ports (40), a snooping module, a transfer information storage unit, a multicast sending module, a failure detector and a port adding module. The snooping module generates snooping information. The snooping information correlates the first communication port (40-10,40-21,40-32,40-43) set to a multicast transfer port to a destination MAC address. The multicast sending module refers to the snooping information stored in the transfer information storage unit and sends a multicast frame received from the layer 2 network, from the correlated multicast transfer port. The failure detector detects a communication failure in the layer 2 network. The port adding module additionally, in response to detection of the communication failure by the failure detector, set the second communication port (40-34,40-41), in addition to the first communication port, to the multicast transfer port.

摘要： In a virtual network apparatus, even when a fault occurs on a private line 112 connecting plural physical network apparatuses 101, 102 to communicate a control signal, the redundancy is maintained, and the lower forwarding capability is prevented. In this network system, a control signal for virtualization to be transmitted and received between plural physical network apparatuses 101, 102 is relayed via a unit spanning LA connecting each physical network apparatus 101, 102 and an adjacent network apparatus 119 in the adjacent network apparatus. Thereby, even when a fault occurs in the private line 112, it is possible to continue to communicate the control signal between the physical network apparatuses 101, 102 and continuously operate the virtual network apparatus.

摘要： In an electronic device, when a 48 V feed system is shifted to a 12 V feed system, in order to supply the same electric power, a current of fourth times needs to flow into a backplane. Also, in an anteroposterior intake and exhaust system, there is a need to form a ventilator through which a cooling air passes in the backplane. Further, there arises a problem that a mechanical strength is deteriorated by provision of the ventilator in the backplane. There is provided a structure in which a pinnate projection is provided on a feed bus bar, and a cooling air is applied to the feed bus bar. Also, the feed bus bar is brought into close contact with an overall surface of the backplane, and electrically and mechanically connected thereto at multiple points, to thereby perform both of cooling and the suppression of stiffness deterioration.
