Example Embodiment

[0037] The following describes the embodiments of the present invention in detail with reference to the drawings.

[0038] See figure 1 , This figure shows a network flow control method working in full duplex mode according to an embodiment of the present invention, including the steps:

[0039] Step S101: After triggering the flow control, each communication node sends a detection packet to the opposite node;

[0040] Step S102: After receiving the detection packet, the communication node sends a response to the opposite node;

[0041] Step S103: After receiving the response, the communication node calculates the time difference between the time of receiving the response and the sending time of the detection packet corresponding to the response, and compares the time difference with a first threshold, When it is compared that the time difference is greater than the first threshold, the rate of sending and receiving data is reduced.

[0042] When it is compared that the time difference...

Abstract

The invention provides a method and a device for controlling the flow of a network working under a full duplex model. The method comprises the following steps that: each communication node transmits a detection packet to an opposite end node after the flow control is triggered; the communication node transmits response to the opposite end node after receiving the detection packet; the communication node calculates the time difference between the time of receiving the response and the time of transmitting the detection packet relative to the response after receiving the response, and compares the time difference with a first threshold; and the communication node reduces the speed of transmitting and receiving data when the time difference is larger than the first threshold. The method can intelligently regulate the speed of transmitting and receiving data according to the network state and effectively solve the influence on client machines when a great number of data is transmitted, is more flexible compared with the method of purely limiting the transmission speed, and can also ensure the proportion reserved for the client machines to use the network bandwidth.

Description

technical field [0001] The invention relates to a network flow control method and device, in particular to a network flow control method and device working in a full-duplex mode. Background technique [0002] At present, due to the increasingly wide application of network data transmission, the occupation of limited bandwidth resources is becoming more and more important in the process of data transmission. The simple method of restricting network traffic is not flexible enough. Proper adjustments with changes in the network will inevitably affect the normal network applications of the client. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a network flow control method and device working in full-duplex mode, which can adjust flow control according to network conditions. [0004] In order to solve the above-mentioned technical problems, the present invention proposes a network flow control method working in full...
