1. A transmission apparatus comprising:
a memory in which control data included in a frame received from outside the transmission apparatus and state information indicating a state of the control data in the transmission apparatus are stored in association with each other; a circuit to execute: detecting the control data from the frame received from outside the transmission apparatus; recording the control data detected to the memory in association with the state information; performing a first changing process of changing, when the recording of the control data is completed, the state information to information indicating that the recording of the control data is completed; determining, when the state information is changed to information indicating that the recording of the control data is completed, whether or not the control data stored in the memory is to be rewritten; rewriting the control data stored in the memory, upon determining that the control data is rewritten; performing a second changing process of changing, when the control data is rewritten, the state information to information indicating that the rewriting of the control data is completed; reading, when the state information is changed to information indicating that the rewriting of the control data is completed, the control data stored in the memory; and inserting the control data, that has been rewritten, into the frame so that the frame including the rewritten control data is transmitted from the transmission apparatus. |
