Abstract
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.
