Abstract:
In a communication apparatus having a plurality of communication media, even when an available communication environment dynamically varies, the occurrence of a communication disconnection due to a switching of communication media can be prevented. There are included a communication media monitoring/diagnosing part (11) that periodically monitors the statuses of communication media possessed by the local terminal and notifies a transmission destination terminal of the monitoring result of the monitored communication media; an association database (14) that holds association information including at least information of both the IP addresses used for communication and the identifiers used for identifying the foregoing communication media and associated with those IP addresses; an association transmitting part (12) that generates a transport packet to which the association information has been added; and an association receiving part (13) that extracts the association information from the received packet and updates, based on the extracted association information, the information stored by the association database (14).
