摘要： A resilient packet network (RPR) device is connected to one or more rings to constitute an RPR network. The RPR device has a storage unit in which a correspondence between RPR device addresses, each indicating an RPR device connected to the one or more rings, and user device addresses, each indicating a user device accommodated in the RPR device, is stored. When the RPR device receives data addressed to a predetermined user device from a user device accommodated in the RPR device itself, if an RPR device address of an RPR device accommodating the predetermined user device is registered in the storage unit, an RPR header, in which the RPR device address is set as a destination RPR device address, is added to the data. The data with the RPR header is transmitted to the RPR network.

摘要： A multiple spanning tree protocol network which does not influence at all MSTI to which VLAN-ID is not added/deleted and does not reconstruct the topology of this MSTI. In the multiple spanning tree protocol network, a plurality of devices are connected via transmission paths, forming a plurality of topologies, and each of the plurality of devices comprises a network identification information processing section for creating network identification information for each topology, a receive section for receiving and extracting the network identification information from an adjacent device, and a topology change detection processing section, comprising a comparison section for comparing the extracted network identification information with the network identification information of the local device generated by the network identification information processing section and detecting the change, and a topology information construction section for reconstructing only the topology of which change has been detected if the comparison section detects the change.

摘要： A mobile terminal device communicates with a base station in one of a power-saving state in which consumption of power supplied from a built-in power supply is suppressed and a normal state in which the consumption of power supplied from the built-in power supply is not suppressed. The mobile terminal device includes a base station detecting unit that detects a maximum-power received-wave base station of which a received-wave power is maximum, a base-station-change detecting unit that detects whether the maximum-power received-wave base station detected by the base station detecting unit is changed, and a power-saving-state transition control unit that controls transition to the power-saving state when the change of the maximum-power received-wave base station is not detected by the base-station-change detecting unit in a predetermined time in the normal state.
