  • Patent number: 11888757
    Abstract: A communication unit (2) communicates with a management apparatus directly or via another communication apparatus. A transfer control unit (4) performs processing of transferring a state change notification that has been transmitted from a first communication apparatus and indicates a state change of the first communication apparatus. A proxy calculation unit (6) performs, when a failure in communication has occurred at the side of the management apparatus, calculation for state management performed by the management apparatus using the state change notification. When a failure in communication has occurred, the transfer control unit (4) outputs a state change notification to the proxy calculation unit (6). When the failure in communication has been resolved, the transfer control unit (4) performs control so as to transmit the result of the calculation by the proxy calculation unit (6) to the management apparatus.

  • Patent number: 10194008
    Abstract: Disclosed embodiments include systems and methods that may promptly confirm performance information about a network element (NE) when the NE is operating as an active system. For example, disclosed embodiments may include one of communication devices that is connected, together with other communication devices, to a network monitoring device. The communication device may use a redundancy configuration with the other of the communication devices and may output, upon the occurrence of a prescribed event, prescribed information to the network monitoring device about what the communication device measured when performing a prescribed operation as an active system. The network monitoring device may monitor a redundancy system for switching the plurality of communication devices between an active system and a standby system. The network monitoring device may also display prescribed information about one of the communication devices when the communication device operates as an active system.

  • Patent number: 5992261
    Abstract: In a shift lever to which operating force for changing a transmission by a driver is applied, a basal end thereof is inserted in a hole formed in a lever holder. Movement of the shift lever in the axial direction is prevented by an elastic member. When large force acts in the axial direction of the shift lever, the elastic member deflects and the shift lever moves in the axial direction, thereby allowing absorption of the load applied to the shift lever.
