    • 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.
    • 成帧器位于传输设备中,该传输设备将光通道的多个时隙分配给每个具有传输优先级的多个逻辑通道,将由多个逻辑通道接收的多个客户信号分配给分配的多个时隙 并且通过使用与所述多个时隙对应的多个光波长的多个光副载波来发送所述多个客户信号,所述时隙分配单元包括:时隙分配单元,在所述时隙分配单元 不使用与分配给具有高传输优先级的逻辑路径的时隙相对应的光波长,将多个时隙中的至少一个时隙分配给具有高传输优先级的逻辑路径,而与未使用的光波长相对应的时隙 避免分配给具有高传输优先级的逻辑路径的时隙。
