Abstract: Data transmission means divides data into one or more transmission packets in units of a predetermined size in conformity with a predetermined protocol, transmits the transmission packets to a reception apparatus, and receives an acknowledgement packet returned from the reception apparatus. Data size acquisition means acquires a data size of transmission data. Acknowledgement reception time acquisition means acquires a reception time of an acknowledgement packet. An available bandwidth calculation means calculates the available bandwidth in a network using the reception time of the acknowledgement packet when a sum of the data sizes of the transmission data in the predetermined time is double or more the predetermined size.
