## Historique du projet et usages

libprotoident is a lightweight network-traffic classification library from the University of Waikato WAND research group. Its niche is application protocol identification using only a small amount of payload from each direction of a flow.

### Historique du projet

The source headers credit the University of Waikato WAND research group and carry copyright years beginning in 2011. The public GitHub repository was created on 2014-03-20, and the README identifies Shane Alcock as author with additional contributors.

The project frames itself as a deliberately limited form of deep packet inspection: it uses the first four bytes of application payload sent in each direction, plus flow metadata, instead of requiring complete packet payload capture.

### Historique d'adoption

libprotoident's adoption is concentrated in packet-trace and traffic-analysis circles rather than broad application development. Its README ties it to `libtrace` and `libflowmanager`, and its bundled tools operate on libtrace trace URIs, including live network-interface sources.

### Modes d'utilisation

The package provides a library API plus command-line tools: `lpi_protoident` identifies flows, `lpi_find_unknown` reports unidentified flows to aid new rule development, and `lpi_arff` emits ARFF output for Weka workflows.

### Pourquoi les passionnés de paquets s'y intéressent

For package maintainers, libprotoident is interesting because it sits between academic network measurement and practical CLI tooling. It pulls in the LibtraceTeam stack and gives users a packaged way to run protocol classification experiments without building the WAND tools by hand.

### Chronologie

- 2011: Source headers identify University of Waikato WAND work beginning in this period.
- 2014-03-20: The public GitHub repository was created.
- 2017-06-28: Version 2.0.11 added many protocols and moved tools to parallel libtrace and libflowmanager 3 compatibility.
- 2020-11-12: Version 2.0.15 added protocols, an industrial-control-systems category, and category lookup APIs.

### Related projects

- libtrace, libflowmanager, Weka, packet-trace analysis tools, and other traffic-classification projects such as nDPI and Zeek occupy adjacent space.
