BGP path propagation inference

Running the tests

We have some tests to check the propagation algorithm in pre-built topologies. Run with:

python3 -m unittest tests/test_bgpsim.py

Basic benchmarking

You can check the runtime of random path inferences on CAIDA's January 2020 graph by using the tests/bench_bgpsim.py script. It reports 5 averages over 32 full inference runs each. Disabling assertions with -O makes the code significantly faster as it is pretty heavy on asserts.

TO-DO

• Write tests for poisoned announcements. The code should work for announcements with poisoning, but there are no tests for this functionality yet.
