摘要： There is provided a protection switching apparatus including: a path management unit to establish a plurality of connection paths for transmitting/receiving packets, and a plurality of protection paths that are able to substitute for the plurality of connection paths, respectively, and to create a protection group including the connection paths and the protection paths; a protection group controller to determine whether failure has occurred on the connection paths, based on path state information for each path included in the protection group, the path state information stored in the protection group table storage, and to issue an instruction for protection switching, according to the result of the determination; and a protection switching unit to perform protection switching of a path in which failure has occurred to a protection path corresponding to the path in which failure has occurred, according to the instruction for protection switching.
