Network congestion control method and device

Abstract

The embodiment of the invention provides a network congestion control method and device, and relates to the technical field of network communication, and the method comprises the steps: obtaining first information reflecting the relations between the number of data packages transmitted by network equipment in a communication network and the number of received acknowledgement characters (ACK) in apreset duration; obtaining second information reflecting the network time delay of the communication network within a preset time length; obtaining the number of lost packets of the communication network within a preset duration; predicting a value of a to-be-adjusted parameter of the network equipment according to the first information, the second information and the packet loss number; and controlling the network equipment to adjust the to-be-adjusted parameter according to the predicted value so as to realize network congestion control. By applying the scheme provided by the embodiment of the invention, a better network congestion control effect can be achieved in different networks.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a network congestion control method and device. Background technique [0002] Due to the limited data processing capability of network equipment, it is difficult for network equipment to process a large amount of data in a short period of time when there is a large amount of data transmitted in the communication network, which will easily lead to a decrease in data transmission efficiency and network congestion. [0003] In the prior art, the network congestion is usually controlled by an algorithm with relatively fixed rules, for example, the network congestion is controlled by the Vegas algorithm. In this case, when the delay of the network exceeds the preset threshold, the size of the CWnd (Congestion Window) of the network device sending data is reduced to half of the original size. The data volume of the data. [0004] Although the application of the above me...

Problems solved by technology

[0004] Although the application of the above method can realize the control of network congestion in some cases, but because the network equipment contained in different communication networks and the data transmitted are different, the reasons for network congestion in different communication networks are often different. Therefore, Algorithms with fixed rules are difficult to achieve better network congestion control effects in different communication networks
