Claim:
1. A bandwidth measuring device comprising: an extracting unit that extracts, as a cutoff frequency, a highest frequency component among frequency components obtained by performing Fourier transform on transition data which indicates a transition of communication congestion traffic with respect to a time in a communication network to be used; a determining unit that determines, on the basis of a relationship between an error ratio and the number of measurement times in a cycle corresponding to the cutoff frequency, a minimum value of the number of measurement times that satisfy a given error ratio; a setting unit that sets each of a measurement cycle and a measurement time so as to satisfy both conditions of a maximum value in the measurement cycle determined on the basis of the cutoff frequency and the minimum value of the number of measurement times in the cycle corresponding to the cutoff frequency determined by the determining unit; and a measuring unit that measures a bandwidth of communication performed by using the communication network, on the basis of the measurement cycle and the measurement time set by the setting unit.
