1. A multiplex transmission apparatus having a plurality of multiplex transmission paths and a plurality of communication nodes connected to the plurality of multiplex transmission paths, each communication node generating at least one of periodic control information and non-periodic control information, comprising:

  • a first multiplex transmission path for performing multiplex transmission of the periodic control information;

    a second multiplex transmission path for performing multiplex transmission of the non-periodic control information;

    first transmission/reception means for transmitting/receiving the periodic control information to/from said first multiplex transmission path;

    second transmission/reception means for transmitting/receiving the non-periodic control information to/from said second multiplex transmission path;

    first determination means for determining whether or not the periodic control information which has been sent from said first multiplex transmission path is a kind of information originally sent from said second multiplex transmission path;

    second determination means for determining whether or not the non-periodic control information which has been sent from said second multiplex transmission path is a kind of information originally sent from said first multiplex transmission path;

    first changing means for changing an object transmission path so that the periodic control information from said first multiplex transmission path is transferred to said second multiplex transmission path when it is determined that the periodic control information is originally sent from said second multiplex transmission path; and

    second changing means for changing an object transmission path so that the non-periodic control information from said second multiplex transmission path is transferred to said first multiplex transmission path when it is determined that the non-periodic control information is originally sent from said first multiplex transmission path.
