CORNIFER

Pre-requisite

Make sure you are runnning python 3.8 or above.
Install pip3.
Install matplotlib, pandas, numpy, scipy or run pip3 install -r requirements.txt. If you are manually installing these packages, you can find the required versions in requirements.txt,

metro-pop-slo: This comprises the latencies for each metro-pop pair at a given percentile. We use the 90th percentile window in our implementation.
topologies: This comprises all the synthetic topologies generated by CORNIFER. All the files are in the format of topology_{size}_{number}, where size represents the number of metro locations in the topology. We have 10 variations of each topology size, and number represents any number between 1 and 10.
results: Once you run CORNIFER, the results will be placed here. It currently has an example output for your reference.

Note that all the latency measurements are synthetic.

Clone the repository.
Run python cornifer.py -s <topology_size> -n <topology_number> to find the virtual WAN placement of topology of size topology_size and variation topology_number. Eg: Running python cornifer.py -s 5 -n 1 with find placement for topology_5_1.csv. This finds placement for l_optimal, k_optimal, mean_k mode, and writes the output under results/{mode}/topology_{size}_{number}.
