Abstract: A 5G or pre-5G communication system is provided to support higher data transmission rates after 4G communication systems such as LTE. To support communication of a terminal that dually accesses a first radio access technology (RAT) communication system and a second RAT communication system, a session generation request message for transmitting traffic is received from a terminal. A target communication system that is to generate a data path with respect to the traffic from the first RAT communication system and the second RAT communication system is determined, the data path for the target communication system is configured, and information about the configured data path is transmitted to the terminal.

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.

Abstract: Methods and apparatuses for controlling transmission control protocol (TCP) send buffers in communication systems are provided. The method includes identifying a current round-trip time (RTT) value and a minimum RTT value in the TCP and adjusting a size of the send buffer based on at least one of a current operation, the current RTT value, and the minimum RTT value in a congestion control scheme according to the TCP.

Abstract: A method for providing a service by a transparent internet cache (TIC) server in a communication network supporting a multipath transport control protocol (MPTCP) is provided. The method includes establishing an MPTCP connection with a user equipment (UE) and an original server through a first network, upon receiving a service provision request from the UE, releasing the MPTCP connection established among the TIC server, the UE, and the original server if data related to a service corresponding to the service provision request is cached, and providing the service corresponding to the service provision request to the UE.
