Abstract
A transmission device is used for a network that includes a plurality of working paths and a plurality of protection paths bypassing a relevant working path for each working paths. The transmission device includes a data plane unit that transmits and receives data to and from other transmission devices; and a signaling processing unit that performs switching, when a signaling message requesting activation to switch to a first protection path corresponding to a first working path is received, from the first working path to the first protection path, wherein, when the first working path is configured as a subset of a second working path and a second protection path corresponding to the second working path is provided, the signaling processing unit performs switching from the first working path to the first protection path and performs switching from the second working path to the second protection path.
