Abstract
A frame generation method in an optical transmission system that transmits a transmission frame including a payload area for storing therein information data and an FEC redundant area for storing therein an error correcting code with respect to the information data is provided, in which coding gain is calculated based on the quality of a communication path through which the transmission frame is transmitted, and, when it is determined that redundancy is insufficient with an error correcting code stored in the FEC redundant area based on the coding gain, a variable parity area for storing therein the error correcting code is set in the payload area and a transmission frame in which the error correcting code is stored in the FEC redundant area and the variable parity area is generated.
