Network fault sensing and positioning method and device, terminal and storage medium

Abstract

The invention discloses a network fault sensing and positioning method and device, a terminal and a storage medium, and the method comprises the steps: carrying out the feature extraction of a data flow passing through a switch, obtaining a flow-level feature, and transmitting the flow-level feature to a classifier according to a preset period; generating inference information of the data stream through a classifier; determining abnormal flow transmission path information according to the inference information, and giving an inference result of the fault position in combination with the abnormal flow transmission path information; the technical problem that end side information is difficult to obtain is solved by performing feature extraction on the data flow passing through the switch and combining data transmission path information to generate inference on a fault position; a flow state classifier of a decision-making tree model is adopted, and the classifier is deployed on a switch, so that the problem that the perception capability of a network side is relatively weak is solved; local inference information is stored in a normal data packet, so that inference aggregation and decision in the network are completed, and the burden of data communication on the network is reduced.

Description

technical field [0001] The invention relates to the field of network fault early warning, and in particular, to a network fault sensing and positioning method and device, a terminal and a storage medium. Background technique [0002] Failure is one of the greatest enemies of a computer network management team. Today's network applications may respond to access requests from tens of thousands of end hosts within tens of milliseconds, or process the computation and distribution of tens of gigabytes of data. This means that if the computer network fails, and the network management team cannot complete the troubleshooting within a short period of time, users will suffer great losses and their experience will plummet. [0003] When a fault occurs in a computer network, if the location of the fault can be located, the subsequent process of solving the fault is often relatively simple. When a fault is sensed, the location of the fault is given. The accuracy and speed of fault pe...
