    摘要： A framer is in a transmission device which allocates a plurality of time slots of an optical channel to a plurality of logical paths each having a transmission priority, allocates a plurality of client signals received by the plurality of logical paths to the plurality of time slots allocated to the plurality of logical paths, and transmits the plurality of client signals by a plurality of optical subcarriers that use a plurality of optical wavelengths corresponding to the plurality of time slots, and includes: a time slot allocation unit that, in a case where an optical wavelength corresponding to a time slot allocated to a logical path having a high transmission priority is not used, allocates at least one of the plurality of time slots to the logical path having the high transmission priority while the time slot corresponding to the unused optical wavelength is avoided, to change the time slot allocated to the logical path having the high transmission priority.
