Traffic Classification Transfer Learning

This project provides code to reproduce the transfer learning experiments from Universal Embedding Function for Traffic Classification via QUIC Domain Recognition Pretraining: A Transfer Learning Success, https://doi.org/10.48550/arXiv.2502.12930.

This project:

  • Loads the pretrained model 30pktTCNET_256 from CESNET Models, with the pretraining procedure detailed in the publication.

  • Transfers the model to seven well-known traffic classification datasets (ten downstream tasks in total) to evaluate how well it generalizes:

    • ISCXVPN2016
    • MIRAGE19
    • MIRAGE22
    • UTMOBILENET21
    • UCDAVIS19
    • CESNET-TLS22
    • AppClassNet
  • Implements three transfer learning methods:

    • k-NN
    • Linear probing
    • Full model fine-tuning
  • Includes training from scratch and an input-space baseline for comparison.

How to Use

  1. Install the dependencies listed in ./requirements/pip-requirements.txt. If you are using Windows, you can create the Conda environment from ./requirements/environment-windows.yml. Ensure that PyTorch is installed with CUDA support. Install faiss either as faiss-cpu or faiss-gpu (pip packages are also available).

  2. Download all datasets

    • MIRAGE19, MIRAGE22, UTMOBILENET21, and UCDAVIS19 are obtained from the tcbench framework. Follow the tcbench instructions to install the datasets.
    • CESNET-TLS22 is accessed via CESNET DataZoo. It is downloaded automatically on first use.
    • Download AppClassNet from figshare.
    • For ISCXVPN2016, we used a version provided by Alfredo Nascita. You can contact him at alfredo[dot]nascita[at]unina[dot]it. Before use, process the dataset with scripts/preprocess_iscx_dataset.py.
  3. Update conf/local-vars.yaml and provide:

    • A local folder containing the AppClassNet and ISCXVPN2016 datasets
    • A temporary directory for experiment outputs
    • A wandb project name (wandb integration for experiment tracking is currently mandatory)
  4. Experiments are configured with Hydra, with configuration files located in ./conf. To run an experiment with a specific configuration, use python -m experiment_wrapper.do_experiment --config-name local-config.yaml.

Results

The results of the experiments are saved in $temp_dir/results. The final results presented in the publication are available in scripts/final-results. For an overview of the results, see scripts/explore_results.ipynb. The best model fine-tuning hyperparameters for each dataset can be found in conf/best.

Traffic Classification Transfer Learning

This project provides code to reproduce the transfer learning experiments from Universal Embedding Function for Traffic Classification via QUIC Domain Recognition Pretraining: A Transfer Learning Success, https://doi.org/10.48550/arXiv.2502.12930.

This project:

  • Loads the pretrained model 30pktTCNET_256 from CESNET Models, with the pretraining procedure detailed in the publication.

  • Transfers the model to seven well-known traffic classification datasets (ten downstream tasks in total) to evaluate how well it generalizes:

    • ISCXVPN2016
    • MIRAGE19
    • MIRAGE22
    • UTMOBILENET21
    • UCDAVIS19
    • CESNET-TLS22
    • AppClassNet
  • Implements three transfer learning methods:

    • k-NN
    • Linear probing
    • Full model fine-tuning
  • Includes training from scratch and an input-space baseline for comparison.

How to Use

  1. Install the dependencies listed in ./requirements/pip-requirements.txt. If you are using Windows, you can create the Conda environment from ./requirements/environment-windows.yml. Ensure that PyTorch is installed with CUDA support. Install faiss either as faiss-cpu or faiss-gpu (pip packages are also available).

  2. Download all datasets

    • MIRAGE19, MIRAGE22, UTMOBILENET21, and UCDAVIS19 are obtained from the tcbench framework. Follow the tcbench instructions to install the datasets.
    • CESNET-TLS22 is accessed via CESNET DataZoo. It is downloaded automatically on first use.
    • Download AppClassNet from figshare.
    • For ISCXVPN2016, we used a version provided by Alfredo Nascita. You can contact him at alfredo[dot]nascita[at]unina[dot]it. Before use, process the dataset with scripts/preprocess_iscx_dataset.py.
  3. Update conf/local-vars.yaml and provide:

    • A local folder containing the AppClassNet and ISCXVPN2016 datasets
    • A temporary directory for experiment outputs
    • A wandb project name (wandb integration for experiment tracking is currently mandatory)
  4. Experiments are configured with Hydra, with configuration files located in ./conf. To run an experiment with a specific configuration, use python -m experiment_wrapper.do_experiment --config-name local-config.yaml.

Results

The results of the experiments are saved in $temp_dir/results. The final results presented in the publication are available in scripts/final-results. For an overview of the results, see scripts/explore_results.ipynb. The best model fine-tuning hyperparameters for each dataset can be found in conf/best.
