A band control apparatus, a band control program and a band control method that control bands takes the cost into consideration. A band control apparatus 1 a for relaying signals by using at least one of a plurality of lines 2 a , 2 b , 3 that is connected to some other band control apparatus 1 b by way of the plurality of lines and adapted to cooperate with the other band control apparatus 1 b to control the bands of the plurality of lines comprises communication status gauging sections 15 a , 15 b , 15 c that gauge the communication status of the own apparatus on the plurality of lines 2 a , 2 b , 3 as first communication status and a band control section 16 that acquires the communication status of the band control apparatus 1 b on the plurality of lines 2 a , 2 b , 3 as second communication status, computationally determines the line status of each of the lines according to the first communication status and the second communication status acquired and allocates the bands to be used for the relay to the plurality of lines 2 a , 2 b , 3 according to the line statuses.
