Abstract:
1. A communication terminal which communicates with at least one communication terminal by using a TCP protocol, the communication terminal comprising: a transmission standby frequency estimation unit that estimates a frequency at which transmission standby is executed since transmission data including a TCP acknowledgement segment arrives at a media access control processing unit of a subject communication terminal until the TCP acknowledgement segment is transmitted to communication media; and a TCP acknowledgement generation control unit that changes a generation frequency of the TCP acknowledgement segment on the basis of the estimated transmission standby frequency information, wherein the TCP acknowledgement generation control unit decreases the generation frequency of the TCP acknowledgement segment when the transmission standby frequency estimation unit estimates that the transmission standby frequency is higher than a predetermined value, and wherein the transmission standby frequency estimation unit includes a received data number calculation unit that calculates the number of received data in a predetermined period, estimates that the transmission standby frequency is high when the number of received data is larger than a predetermined value, and estimates that the transmission standby frequency is low when the number of received data is smaller than the predetermined value, on the basis of the number of received data in the predetermined period.
