1. A method, executed by a computer, the method comprising:

  • receiving a reservation request, from a terminal device, regarding a bandwidth of a line;

    first determining whether a total bandwidth of a bandwidth demanded by the reservation request in a time slot which is specified by the received reservation request and a guaranteed bandwidth to one or more different reservation requests exceeds an upper limit value of the line;

    when the total bandwidth exceeds the upper limit value, calculating a reducible bandwidth based on a bandwidth shortage produced by subtracting the permissible upper limit value from the total bandwidth and statistical information of a use bandwidth in the time slot in the past for the one or more different reservation requests;

    reducing the guaranteed bandwidth based on the calculated reducible bandwidth; and

    assigning the bandwidth demanded by the reservation request to a bandwidth reduced from the guaranteed bandwidth.
