Method, device and system for regulating data traffic

Abstract

The embodiment of the invention provides a method, a device and a system for regulating data traffic. The method comprises the following steps: firstly, receiving bandwidth instruction information used for instructing the transmission bandwidth of a data receiver; then acquiring the transmission bandwidth of the data receiver according to the bandwidth instruction information; and then regulating the data traffic sent to the data receiver according to the acquired transmission bandwidth. Following the steps, the received data traffic can be regulated adaptively according to the change of the data receiver, that is the communication equipment transmission bandwidth, thereby not only the congestion of the internal flow in the communication equipment is avoided and the stability of the service transmission is guaranteed, but also adverse effect brought to the high priority service transmission is avoided and the transmission performance of a system is enhanced.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a method, device and system for regulating data flow. Background technique [0002] At present, in many communication devices, the transmission bandwidth of the communication device can be adjusted in real time according to the transmission conditions of the channel of the communication device to adapt to the change of the channel condition. Such as figure 1 Shown is a schematic diagram of the transmission bandwidth of communication equipment changing with channel conditions. In the figure: when the transmission conditions of the channel are relatively good, such as in sunny weather, a larger transmission bandwidth can be configured to support various business applications. Transmission work; and when the transmission conditions of the channel are relatively poor, such as in rainy weather conditions, a smaller transmission bandwidth must be configured to adapt to the harsh t...

AI Technical Summary

Problems solved by technology

[0006] To sum up, in the process of implementing the present invention, the inventors found that there are at least the following problems in the prior art: in the prior art solution, the communication device cannot accurately and adaptively adjust the received data according to the change of its own transmission bandwidth. Data traffic, which may cause internal traffic congestion; at the same time, it will also affect high-priority business transmission, reducing the transmission performance of the system
