摘要： A transmission device includes an ingress edge device that receives a frame, an egress edge device having a plurality of destination addresses, and a rewrite unit that rewrites a destination MAC address of the frame to another destination MAC address of the egress edge device when detecting a failure on a working path between the ingress edge device and the egress edge device.

摘要： A signal transmission method includes causing each of a plurality of nodes to transfer, using the actually used line, a second signal in a second layer, in which one or a plurality of first signals in a first layer are contained, to a node adjacent in the first or the second direction when each of the plurality of nodes transmits or receives the first signal, when no failure occurs in a transmission path in a network, and causing a first node, located at an end of a failure point, to switch a transmission direction of the second signal and to send out the second signal to the backup line, and causing a second node, which is a transmission source or a reception destination of the first signal, to select one of the first and second directions, when a failure occurs in the transmission path in the network.

摘要： A transmission apparatus includes a processor configured to recognize a number of working failures and a number of protection failures on a network for transmission of wavelength-multiplexed signal light, the number of working failures being the number of failures in signal light in wavelengths at a working entity and the number of protection failures being the number of failures in signal light in wavelengths at a protection entity, configured to perform path switching for each group of signal light in wavelengths that are different from each other and configured to select, when multiple failures occur, restoration processing, on a basis of the number of working failures and the number of protection failures.
