  • CALCULATOR, COMMUNICATION CONTROL METHOD, AND COMPUTER-READABLE RECORDING MEDIUM
    Publication number: 20140173101
    Abstract: A calculator includes communication devices, a detection unit, and a communication control unit. The detection unit performs communication among the plurality of communication devices connected to the same segment in a network, to thereby detect division of a network connected to each communication device. In the case division of the network is detected by the detection unit, the communication control unit generates information about a correspondence relationship between each communication appliance and an appliance in a reachable network. The communication control unit performs communication between a communication device and an appliance in a network based on the information about a correspondence relationship.
