Method and apparatus for controlling send buffer of transmission control protocol in communication system
First Claim
Patent Images
1. A method for controlling a send buffer of a transmission control protocol (TCP) in a communication system, the method comprising:
- identifying a current round-trip time (RTT) value and a minimum RTT value in the TCP;
determining whether a current operation in a TCP congestion control scheme is a slow start operation or a congestion avoidance operation;
adjusting a size of the send buffer by multiplying a size of a congestion window with a predetermined constant if the current operation corresponds to the slow start operation; and
adjusting the size of the send buffer based on a difference between the current RTT value and the minimum RTT value if the current operation corresponds to the congestion avoidance operation.

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.
