Example Embodiment

[0020] In view of the problems existing in the prior art, the present invention proposes an improved network congestion control scheme, which can improve the accuracy of adjustment timing.

[0021] In order to make the technical scheme of the present invention clearer and more comprehensible, the scheme of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] figure 1 It is a flowchart of an embodiment of a network congestion control method of the present invention. Such as figure 1 Shown, including:

[0023] Step 11: When it is determined that network congestion occurs, determine the transmission control protocol (TCP, Transmission Control Protocol) data flow that needs to be adjusted and the adjustment target of each TCP data flow that needs to be adjusted according to the current congestion situation;

[0024] Step 12: Adjust each TCP data stream to be adjusted according to the corresponding adjustment ...

Abstract

The invention discloses a network congestion control method. The method comprises the following steps: when it is determined that network congestion occurs, according to a current congestion condition, determining TCP data flows needing to be adjusted and the adjusting object of each TCP data flow needing to be adjusted; and according to the corresponding adjusting objects, respectively adjusting each TCP data flow needing to be adjusted. The invention simultaneously discloses a network congestion control apparatus. By applying the scheme provided by the invention, the accuracy of adjusting opportunities can be improved.

Description

technical field [0001] The invention relates to mobile network technology, in particular to a network congestion control method and device. Background technique [0002] When there are many packets in the mobile network, the performance of the network will decrease, that is, network congestion will occur. [0003] Correspondingly, in order to improve the performance of the network, certain measures must be taken to solve the problem of network congestion, that is, network congestion control. [0004] The core idea of ​​the traditional network congestion control method is to use end-to-end transmission feedback information, such as packet loss and delay, to repeatedly test and match the current network path status, and constantly adjust the size of the sending window. [0005] However, the medium of the wireless channel determines that its link is extremely susceptible to interference, prone to temporary packet loss and delay jitter, etc. Therefore, the end-to-end congestion...
