An available bandwidth estimation device (300) comprises a transmission rate acquisition unit (301) that acquires a transmission rate, which is a quantity of data that a transmission device transmits in unit time to a receiving unit that is connected via a communications network to be capable of communication; and an available bandwidth estimation unit (302) that estimates available bandwidth on the basis of a mathematical model and the acquired transmission rate; wherein the mathematical model is built by representing the relationship between the transmission rate and the available bandwidth, which is the communications bandwidth that can be used upon a communications path between the transmission device and the receiving device, with a mechanical model that includes a mobile body capable of moving in a preset direction of movement and an elastic body that deforms in the direction of movement by the degree of movement that the mobile body moves in the direction of movement. |
