A communication terminal which sets a communication session between a plurality of communication terminals through a network to perform data transmission and reception includes a measuring unit which measures round-trip delay time (RTT) or one-way delay time between the communication terminals for performing transmission and reception on the basis of the received acknowledgement, a reception bandwidth measuring unit which measures a reception bandwidth in a reception terminal of the communication terminals on the basis of the received acknowledgement, a correcting unit which corrects a value of the round-trip delay time or the one-way delay time by using at least the reception bandwidth, and a transmission bandwidth determining unit which determines a transmission bandwidth on the basis of the value of the corrected round-trip delay time or the corrected one-way delay time.
