Abstract: The present disclosure relates to a 5G or pre-5G communication system to be provided for supporting a data transmission rate higher than that of a 4G communication system such as an LTE. The present invention relates to a method by which a proxy sets an initial window value in a wireless communication system, the method comprising: splitting a transmission control protocol (TCP) connection between a terminal and a server; extracting the information related to the terminal from the data received from the terminal; and setting the initial window value on the basis of a round trip time (RTT) value and a throughput value for each of terminal groups grouped on the basis of the information related to the terminal.

Abstract: The present disclosure relates to a 5G or pre-5G communication system for supporting a higher data rate beyond a 4G communication system such as LTE. In addition, the present disclosure relates to a TCP-based transmission control method and apparatus which can reduce a delay time while improving a transmission rate in a communication system. A method for TCP-based transmission control in a communication system according to an embodiment of the present disclosure comprises the steps of: determining a maximum target transmission rate for TCP control using maximum congestion windows (CWNDs) estimated at predetermined times; determining a minimum target round trip time (RTT) for the TCP control using minimum RTTs estimated at the predetermined times; and updating at least one of a congestion window (CWND) and a receive window (RWND) in an RTT time slot, using the maximum target transmission rate and the minimum target RTT.
