<p>A communication apparatus (1), which has a currently used system of communication path and a reserve system of communication path both established to communicate with an opposed communication apparatus, comprises a switching control unit (13) that, when having selected, as a selected path, one of the communication paths and using the selected path to perform a data transmission, determines, based on a traffic flow amount, whether the selected path exhibits a heavy traffic and that, when having determined that the selected path exhibits a heavy traffic, selects some of transport data as to-be-switched data and then switches the transmission path of the to-be-switched data to the communication path other than the selected path.</p> |
