If you're working on a Community ID implementation, you can use the data in this folder to verify the correctness of your implementation. We provide two sets of data: tables for cherry-picking specific tuples, and JSON files for programmatic verification.
The following three tables show correct Community ID results for basic configurations. Regular tables render poorly on GitHub so the following embeds them as code. You may want to refer to the source of this README directly or look at the make-tables.py script in this folder, which generates them.

The baseline_*.json files in this folder contain JSON data that
summarize flow tuples and corresponding Community ID values. They're
produced by running the community-id-pcap
tool from the pycommunityid package on the pcaps/combined.pcap.gz
file in this repo, with the same configurations as for the above
tables. make-json.sh generates them.
