摘要： An apparatus stores information identifying unallocated channels for each of spans, where a span indicates a section between adjacent nodes of a plurality of nodes in a communication network. The apparatus extracts unallocated channels for each of all spans provided between a start point node and an end point node of a path in the communication network, by referring to the information, and determines a channel including consecutive unallocated spans which are arranged on routes including the path and spans outside the path, and whose number is minimum among the extracted unallocated channels, as a channel to be set to the path.

摘要： An optical transport network system includes a plurality of NEs, each transmitting wavelength-multiplexed optical signals. Each NE includes a routing information DB that is used to store reachable area information, which contains identifiers of other NEs in a range within which the optical signals can be transmitted from the own NE without using an REG. A FROM NE includes a path candidate searching unit that searches for a plurality of path candidates for transmitting optical signals from the FROM NE to a TO NE. The TO NE includes a path selecting unit that selects a path for transmitting optical signals from among a plurality of path candidates. The path selecting unit obtains the number of times for which the REG is used for each of the plurality of path candidates; and, based on each number of times that is obtained, selects a path for transmitting the optical signals.

摘要： A transmission apparatus includes a plurality of output units and a detector. The plurality of output units is configured to couple to a plurality of transmission paths, respectively, branched from one transmission path. The plurality of output units includes at least one first output unit configured to transmit signal light selectively to one of the branched transmission paths, and at least one second output unit configured to transmit test light with a wavelength different from a wavelength of the signal light to another of the branched transmission paths. The detector is configured to decide a failure in the branched transmission paths, based on a result of detection of a reflected light of the test light received through at least one of the branched transmission paths.
