Title:
ABNORMAL TRAFFIC MONITORING METHOD AND APPARATUS, AND DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/072887
Kind Code:
A1
Abstract:
Provided are an abnormal traffic monitoring method and apparatus, and a device and a computer-readable storage medium. The method comprises: collecting user access records; performing cleaning on and compiling statistics on original data to generate first traffic time sequence data; performing multi-scale wavelet decomposition on the first traffic time sequence data to obtain a wavelet coefficient of each layer; taking the wavelet coefficient of each layer as an analysis object, establishing a corresponding stationary time series model and performing prediction to obtain a predicted wavelet coefficient of each layer; performing wavelet reconstruction on the predicted wavelet coefficient of each layer to obtain second traffic time sequence data; taking the second traffic time sequence data as a predicted traffic value, and comparing an actual traffic value and a predicted traffic value corresponding to the same time; and if the actual traffic value is within a confidence interval of the predicted traffic value, determining that the current network traffic is normal, otherwise, determining that the current network traffic is abnormal. By means of the method, the accuracy of abnormal traffic monitoring is improved, and the deployment cost is reduced.
