Claim 7:
8. The signal transfer method according to claim 7, wherein,
in a case in which an amount of low-priority traffic to be transmitted during a predetermined period is smaller than an amount of low-priority traffic that can be transmitted during the second transmission period estimated for each of the plurality of paths, the estimating includes:
using, for a different best effort-type low-priority traffic flow, a band obtained by subtracting an amount of low-priority traffic to be transmitted from a band of the second transmission period, after determining or changing the plurality of paths for low-priority traffic; and
determining the plurality of paths to maximize a transmission available band per the different best effort-type low-priority traffic flow, and
in a case in which the amount of low-priority traffic to be transmitted during a predetermined period is larger than the amount of low-priority traffic that can be transmitted during the second transmission period estimated for each of the plurality of paths, the estimating:
calculating a probability density function with which each of the plurality of paths corresponds to the second transmission period; and
determining the plurality of paths for low-priority traffic based on the probability density function to maximize a probability of accommodating the low-priority traffic.
