# Connection Coalescing - Aggregate Data

This repository contains the aggregate data and the scripts needed to re-generate
every plot in the accepted IMC'22 paper, titled "Respect the ORIGIN! A Best-case Evaluation of Connection Coalescing in the Wild".

_By: Sudheesh Singanamalla, Muhammad Talha Paracha, Suleman Ahmad Jonathan Hoyland, Luke Valenta, Yevgen Safronov, Peter Wu, Andrew Galloni, Kurtis Heimerl, Nick Sullivan, Christopher A. Wood, Marwan Fayed_

## Reproducing the Figures in the Paper

```shell
$ python generate.py
```

The raw dataframes needed for each plot is available in `data` and the generated figures
are stored in the `plots` directory.
