Abstract:
A communication control apparatus for controlling communication between at least one communication apparatus and a network apparatus residing on one network among a plurality of networks includes multiple communication controllers respectively provided for the plurality of networks. Each communication controller includes a memory that stores operation determination information to be used for determining processing to be performed on transmission-and-reception information, the transmission-and-reception information to be transmitted or received by the communication controller with respect to other communication controller or the network apparatus on the network and circuitry that acquires the operation determination information in response to receiving the transmission-and-reception information, and performs operation corresponding to the acquired operation determination information on the transmission-and-reception information. Each of the multiple communication controllers controls communication between the communication apparatus and the network apparatus residing on the network by performing the operation corresponding to the acquired operation determination information.
Abstract:
A communication system includes transmission apparatuses and a reception apparatus. Each transmission apparatus includes a data input processing unit to which data is input, a first controller that performs a control process for transmitting the data, and a first wireless communication processing unit that transmits the data to the reception apparatus according to the control process performed by the first controller. The first controller performs a control process for causing another transmission apparatus to transmit data input to the other transmission apparatus to the reception apparatus. The reception apparatus includes a second wireless communication processing unit that receives data from one of the transmission apparatuses, a second controller that performs a control process for outputting the received data, and a data output processing unit that outputs the received data according to the control process performed by the second controller.
Abstract:
