摘要： The present invention relates to a communication path calculation method and module. More particularly, the present invention provides a communication path calculation method and module that are implemented or incorporated in a transmission apparatus including a ROADM or the like which performs WDM communication, advertises information on a wavelength which can be added or dropped, as information on a link, and uses the information to autonomously calculate a communication path. Optical transmission equipment that is accommodated in a WDM network over which a wavelength-division multiplexed signal is transferred includes a reconfigurable OADM module. For calculation of a communication path, the OADM module creates a link table listing clients of the own equipment and connected WDMs, and advertises the link table to the other pieces of equipment accommodated by the network as pieces of information on restrictions to be imposed on routing from the own equipment. The other pieces of equipment each receive and store the advertised pieces of information on restrictions to be imposed on routing, and use the pieces of information as pieces of information on restrictions to be imposed on a calculation to calculate a communication path from the own equipment.

摘要： A communication apparatus stores therein link information indicating a network connection status of an entire hierarchical network, collects link information indicating a network connection status in its own area in predetermined cycles, and transmits the collected link information to another area assigned a level different from a level assigned to its own area. When receiving link information from another area assigned a different level, the communication apparatus determines whether the received link information is new link information newer than link information stored in a predetermined storage unit; when it is determined that the received link information is new link-information, the communication apparatus stores the new link information into the predetermined storage unit and advertises it in its own area; by contrast, when it is determined that the received link information is not new link-information, the communication apparatus discards the received link information without storing and advertising.
