Abstract
A communication device transmits a plurality of measurement packets for identifying an available bandwidth to another communication device connected via a network, using bandwidths in the measurement bandwidth range. The communication device then determines whether the available bandwidth is included in the measurement bandwidth range. In a case where the available bandwidth is not included in the measurement bandwidth range, the communication device determines whether the available bandwidth is located on a narrowband side or on a wideband side with respect to the measurement bandwidth range, and determines a bandwidth shift amount based on an amount of change. The communication device updates the measurement bandwidth range by shifting one of the lower bandwidth and the upper bandwidth based on the bandwidth shift amount.
