CESNET-TLS22

Overview

• Built from the traffic of the CESNET2 network observed during the first two weeks of October 2021.
• Contains 141 million flow records.
• Has 191 service labels (e.g., Windows Update, Google Search, Instagram, Dropbox).
• Contains two types of data: packet metadata sequences and flow statistics.

Citation

We published a paper in the Computer Networks journal that introduces the CESNET-TLS22 dataset in more detail and uses the dataset for researching the classification of web services in TLS traffic. If you use this dataset, we would appreciate a citation to the following paper: https://doi.org/10.1016/j.comnet.2022.109467.
