Control method and device for network congestion

Abstract

The invention discloses a control method and a device for network congestion. The control method for the network congestion comprises the following steps: in allusion to a network transmission environment, allocating different buffering queues for different types of data transmitted in the network transmission environment; and in allusion to different types of transmitted data flows, the following operations can be carried out: confirming a average depth value of the queue capacity in a current transmission period of the buffering queue; and confirming a first depth identity value and a second identity value, wherein the first identity value and the second identity value are allocated to the buffering queue of the type of data flow, and controlling the type of data flow to enter the buffering queue which conducts a configuration for the type of data flow according to the relations among the average depth value of the queue capacity, the first identity value and the second identity value, so that the control of the network congestion can be better achieved, network service quality can be improved and perceptibility of users can be improved.

Description

technical field [0001] The invention relates to the technical field of communication network management, in particular to a method and device for controlling network congestion. Background technique [0002] With the continuous development of communication technology, especially the penetration of wireless local area network technology into the traditional information communication field, the data transmission volume in the communication network has doubled. In the multi-core high-speed centralized forwarding link in the communication network, due to the accumulation of a large number of data services, it will cause network congestion and lead to network collapse. Therefore, the network quality of service (QOS, Quality of Service) management of the centralized forwarding link in the communication system becomes particularly important for solving network congestion. [0003] In the prior art, there are mainly the following two methods for the QOS management method of the cen...

Problems solved by technology

[0007] For the first method, because the tail drop management method is a passive management method, in the process of data transmission, it is easy to cause the buffer queue to be full due to the sudden high flow of certain types of data, while other types of data cannot pass through. The deadlock phenomenon causes waste of network transmission resources

[0008] For the second method, although the phenomenon of full queue and deadlock can be avoided, in the process of data transmission, different types of data have different priority levels, and the method of RED is used to realize the QOS management of the centralized forwarding link. Type of data adopts the same standard control threshold, so it is difficult to guarantee the fairness of data transmission

[0009] The two methods of controlling network congestion used in the above-mentioned prior art, the control method is simple and rough, which will easily lead to the reduction of QOS and the waste of network transmission resources, and the network congestion control method that does not distinguish the priority level of data types is also It will bring restrictions on network traffic, thereby reducing the quality of network service, which in turn affects user perception
