Abstract

A signal transfer control apparatus that performs a control operation to switch a plurality of communication paths constituted by a plurality of signal transfer apparatuses transferring a signal includes: a fixed delay information acquisition unit that acquires fixed delay information for each of the plurality of communication paths; a traffic information acquisition unit that acquires traffic information indicating a traffic volume or each of the plurality of communication paths; a probability density function estimation unit that estimates a probability density function of a traffic volume of each of the plurality of communication paths based on the traffic information; an occurrence probability estimation unit that estimates an occurrence probability of variable delay in each of the plurality of communication paths based on the probability density function of each of the plurality of communication paths; a communication path calculation unit that performs a calculation for specifying a communication path which is highly likely to satisfy a predetermined delay condition based on the occurrence probability of the variable delay in each of the plurality of communication paths and the fixed delay information for each of the plurality of communication paths; and a setting instruction unit that outputs a setting instruction for switching a transfer destination of a signal to at least any one of the signal transfer apparatuses so that the signal is transferred via the communication path specified by the calculation performed by the communication path calculation unit.
