Abstract

Embodiments of the present invention provide a method and device for determining a receiving window in TCP flow control, the method comprising: the communication device acquires the data processing rate of the communication device and the amount of data accumulated in the receiving buffer of the communication device; The data processing rate is the amount of data processed by the communication device in the round-trip time delay RTT; then according to the data processing rate and the amount of data accumulated in the receiving buffer, determine the receiving window of the communication device, thereby realizing Dynamically adjust the receiving window, and at the same time make full use of the data processing capability of the communication device, and avoid excessive backlog of data in the receiving buffer.

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...
