Exp_datasets

Two multivariate time series (structured CDN KPIs) datasets are used in our work (folders named dataset1 and dataset2) which span 78 days and 64 days respectively.
These two datasets are collected from two different provincial-level CDN edge sites of a top ISP-operated CDN.
There are 7 abnormal sequences in dataset 1 and 5 abnormal sequences in dataset 2.
These labelled abnormal sequences are confirmed by human operators. So they can be considered as the ground truth.
The KPIs in the datasets include the out-bound traffic and in-bound traffic of CDN servers, cache hit ratio, average bitrate, and so on.
For privacy reasons, these KPIs are anonymized and normalized.
