The CLD-Net model uses a feature-reduction step that compresses high-dimensional CNN+LSTM representations to 8 dimensions corresponding to 8 traffic classes, enabling efficient multi-class classification without class-specific hand-tuning.

Implications

Compact latent-space classifiers generalize across traffic classes from a single training run; adding a new circumvention protocol does not require censors to rebuild the entire pipeline — only to retrain with new labeled samples.
Circumvention tool designers should assume that a censor with an existing ML pipeline can add detection of a new protocol quickly once labeled traffic samples are available.
