HybridMon prototype implementation

Description

This repository contains the code of our HybridMon prototype.

If you use any portion of our work, please cite our paper:

}

Execution

1. Configure bfrt_setup.py according to your setup, i.e., sending and collecting machines/interfaces (see dummy entries for src and dst)
2. run bfrt_setup.py
3. run run_pd_rpc.py

Remark on our use of PRECISION

HybridMon implements PRECISION for subsampling as proposed by Ben Basat et al.:

@article{basat2020precision,
    title={Designing Heavy-Hitter Detection Algorithms for Programmable Switches},
    author={Basat, Ran Ben and Chen, Xiaoqi and Einziger, Gil and Rottenstreich, Ori},
    journal={IEEE/ACM Transactions on Networking},
    volume={28},
    number={3},
    year={2020},
    publisher={IEEE}
}

At the time of implementing HybridMon, no Tofino implementation of PRECISION has been available. It was only released after. As a result, the parts of our source code concerning subsampling are based on the ideas from the paper above, but have been independently implemented with our own research goals in mind. To conclude, our implementation does not use any code fragments of PRECISION's original implementation.
