Problems solved by technology

[0005] After research, when the above-mentioned technology is used to send the message from the network device to the next-hop device, there will be the following problems: After the network device receives the target message, it will determine the QoS priority of the target message according to the QoS priority of the target message. The target queue corresponding to the message; then cache the target message in the target queue to wait for processing
In this way, the transmission delay of the target message will continue to accumulate, which may eventually affect the service quality of the service to which the target message belongs.

Abstract

The present application provides a data transmission method and network device, and relates to the field of communications. The present application can avoid, as far as possible, the situation that the target packet is continuously congested at multiple transmission nodes in the transmission path during the transmission process. The method includes: acquiring a target message. When it is detected that the length of the target queue reaches the preset threshold value, a re-marking packet is generated. The service data carried by the re-marked message and the target message are the same. The re-marking message includes a second priority field for indicating the QoS priority of the re-marking message, and the QoS priority indicated by the second priority field is higher than the QoS priority indicated by the first priority field. The target queue includes: a queue corresponding to the target packet determined according to the QoS priority of the target packet in the first network device. In response to generating the re-marking message, the re-marking message is sent to the second network device. This application applies to data transmission.

Description

technical field [0001] The present application relates to the field of communications, and in particular, to a data transmission method and network device. Background technique [0002] With the development of information technology, an endless stream of new services and new application scenarios emerge as the times require, which leads to an increasing amount of data traffic in communication networks. Furthermore, the problem of network congestion has gradually become one of the common reasons for the degradation of network service quality. [0003] At present, a common method to control network congestion is as follows: [0004] When a device interface in a network device is congested, the packets that need to be processed by the device interface are first buffered, and then the device interface sends the buffered packets to corresponding subsequent devices in sequence. Wherein, when a packet is buffered, the packet is allocated to a queue corresponding to the packet in ...
