Abstract:
1. A communication apparatus which carries out data transmission in such a manner that transmission data is distributed to a predetermined plurality of data transmission circuits, comprising: a standby circuit generating part configured to determine, when a predetermined condition is satisfied, a predetermined circuit from among the plurality of circuits as a standby circuit, wherein, when a working circuit other than the standby circuit becomes not usable, transmission data passing therethrough until then is transferred to the standby circuit; and a standby circuit releasing part configured to use the standby circuit as a working circuit when a load total value in the predetermined plurality of data transmission circuits increases, wherein: for generating the standby circuit, said standby circuit generating part obtains a predetermined distribution determination value from multiplying a value obtained based on a number of current working circuits with a predetermined lower limit value, and generates the standby circuit in a case where the load total value is smaller than the predetermined distribution determination value, for releasing the standby circuit, said standby circuit releasing part obtains a predetermined standby circuit releasing determination value from multiplying the value obtained based on the number of current working circuits with a predetermined upper limit value, and releases the standby circuit in a case where the load total value is larger than the predetermined standby circuit releasing determination value, said standby circuit generating part carries out generation of the standby circuit by transferring transmission data of a circuit having a lowest load rate to a circuit having a second lowest load rate; and said standby circuit releasing part carries out releasing of the standby circuit by transferring transmission data of a circuit having a highest load rate to the standby circuit.
