Abstract: PURPOSE: A channel reallocation method for a path through and an add/drop of an optical transmission apparatus is provided to utilize a channel capacity of each ADCU in maximum by freely changing the sequence of a path through connection and add/drop connection using a channel reallocation method. CONSTITUTION: Each ADCU of an optical transmission apparatus is classified into upper and lower 8 channels and allocates a path through channel to the upper 8-channel of the ADCU and an add/drop channel to the lower 8-channel. It is checked whether the connection type is the add/drop or path through in case that there is a new connection request. In case that the connection type is the add/drop, the channel which is not occupied among the lower channels of the ADCU which performs the add/drop connection is searched, and the add/drop connection is performed. In case that the lower channels of a corresponding ADCU are all occupied, the upper channel of a corresponding ADCU is searched, and the add/drop connection is performed. In case that the upper and lower channels of the ADCU are all occupied, the channel occupied by the path through connection among the channels of each ADCU are reallocated to other ADCU, and the requested add/drop connection is performed.
