1. A band estimation device that calculates a necessary band of a link between communication devices in a communication system in which a plurality of lines is accommodated in the link, the necessary band improves band utilization efficiency, the band estimation device comprising
a communication unit to which a contracted band for each line, a traffic amount of the link in an observation period, and a contracted band for each line in a future design period are input, and
an arithmetic processing unit that
creates a machine learning model for performing machine learning on the contracted band and the traffic amount for each time in the observation period and predicting a probability density function of the traffic amount from the contracted band,
estimates the probability density function of a future traffic amount for each time in the design period by applying the contracted band for each line in the design period to the machine learning model,
applies a desired confidence interval to the probability density function for the future traffic amount, where a lower limit of the desired confidence interval indicates a lowest likely amount of future traffic and an upper limit of the desired confidence interval indicates a highest likely amount of future traffic, and
sets the upper limit of the desired confidence interval as the necessary band of the link between communication devices in the communication system.
