nDPI Source Code

The results from all heuristic engines (lPI, nDPI and go heuristics) get dedpulicated automatically. Future versions could create a certainity score based on the number of votes from different heuristics.

DPI is currently used to indicate which applications have been seen for which IPProfile, when using the DeviceProfile encoder.

Platform Support

NETCAPs DPI integration is currently only available on linux and macOS.
