Claim of US Patent No. 10,117,245

1. A transmission apparatus comprising:a first transmission section that transmits communication data through a first communication path using a period in which cyclic data is transmitted among the communication data and a period in which acyclic data is transmitted among the communication data, the cyclic data being transmitted cyclically and the acyclic data being transmitted acyclically;
a second transmission section that transmits the communication data through a second communication path by performing priority control depending on the priority of the communication data;
a switching control section that performs switching between the transmission using the first transmission section and the transmission using the second transmission section; and
a parameter setting section that sets communication parameters for the second transmission section in the case that switching is performed by the switching control section from the transmission using the first transmission section to the transmission using the second transmission section, the parameter setting section including:
a transmission pattern derivation section that derives, from the communication data transmitted using the first transmission section, transmission patterns of the cyclic data transmitted cyclically, and that derives, from the communication data transmitted using the first transmission section, transmission patterns of the acyclic data transmitted acyclically; and
a parameter derivation section that derives the communication parameters on the basis of the transmission patterns of the cyclic data and the transmission patterns of the acyclic data derived by the transmission pattern derivation section, the communication parameters indicating to allocate a band to the cyclic data prior to the acyclic data.
