Abstract:
1. An optical transmission device that sets bandwidths of optical communication channels for inputting and outputting data in a time-division multiplexed optical network that uses Generalized Multi-Protocol Label Switching, the optical transmission device comprising: a switching unit that switches bandwidths used by the optical communication channels in an optical transmission channel connecting to an adjoining optical transmission device, each of the bandwidths corresponding to a time slot in the time-division multiplexed optical network; a detecting unit that detects a non-continuous bandwidth used by at least one of the optical communication channels in the optical transmission channel, the non-continuous bandwidth indicating a bandwidth between two of the bandwidths that are not used as an optical communication channel; and a bandwidth adjusting unit that controls the switching unit to rearrange the detected non-continuous bandwidth into a continuous bandwidth for the optical communication channels.
