Patent ID: 8477591

Claim:
A control apparatus of a communication system that uses a plurality of communication paths from a transmission node to a reception node to redundantly transmit data, the control apparatus comprising: an acquisition unit constructed to acquire transmission data transmitted by a communication frame; a setting unit constructed to divide the transmission data into a plurality of partial data and to set priorities to the plurality of partial data; a calculation unit constructed to calculate a time slot number which is required to transmit the partial data on the communication paths; a selection unit constructed to select one or more combinations of the partial data and the communication paths based on the priority of the partial data and the required time slot number; a determination unit constructed to determine access management information defining the partial data to be transmitted in a time slot of the communication frame and at least one of the communication paths used in the transmission, based on the selected one or more combinations; and a notification unit constructed to notify nodes included in the communication system of the access management information, wherein the selection unit selects the one or more combinations in descending order of the priorities of the partial data and selects the one or more combinations in ascending order of the required time slot number if the priorities of the partial data are equal, wherein each of the acquisition unit, the setting unit, the calculation unit, the selection unit, the determination unit, and the notification unit is implemented by using one or more processors, and wherein the one or more processors is coupled to a memory.
