abstract = {The rapid adoption of encryption protocols such as TLS and VPN has rendered traditional port-based and payload-based traffic classification techniques ineffective. This paper presents a framework for encrypted traffic classification leveraging statistical flow features, byte distributions, and protocol metadata. We propose a preprocessing pipeline that converts raw PCAP network traffic into feature-rich tabular datasets and evaluates classification performance using deep neural networks (DNNs) and a baseline Boost model. Experiments on the ISCXVPN2016 dataset demonstrate the high discriminative power of the proposed feature set. The Boost classifier achieved a high accuracy of 93.12% and a macro F1-score of 90.79% on a 12-class task, outperforming the implemented DNN, which attained 82.59% accuracy and a 79.28% macro F1-score. While the method is effective in distinguishing VPN vs. non-VPN flows and major applications, classification performance is challenged by traffic categories with overlapping characteristics such as P2P and streaming.},
