Abstract

The embodiment of the present invention provides a determination method and device of a reception window in the TCP flow control. The method comprises the steps of using a communication device to obtain the data processing rate of the communication device and the data quantity accumulated in a reception buffer area of the communication device, wherein the data processing rate is the data quantity processed by the communication device in the round-trip time (RRT); then determining the reception window of the communication device according to the data processing rate and the data quantity accumulated in the reception buffer area, so that the reception window is adjusted dynamically, at the same time, the data processing capability of the communication device is utilized fully, and the excessive accumulated data in the reception buffer area is avoided.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular to a method and device for determining a receiving window in TCP flow control. Background technique [0002] At present, the purpose of the transmission control protocol (English: Transmission Control Protocol, referred to as: TCP) flow control is to allow the receiving end to only allow the sending end to send the data that the receiving end can accept, so as to prevent the excessively fast sending end from causing the slower receiving end to fail. Receive buffer overflow. At present, TCP flow control can be performed through the receiving window. The receiving window indicates the maximum size of data that the receiving end can receive within a round-trip delay (English: Round-Trip Time, RTT for short). Therefore, the sending end can be based on The receiving window of the receiving end sends data that does not exceed the size of the receiving...
