This repository provides the generral augmentation procedure, using a TSN schedule as an input and prolonging/deferring its transmission slots to account for the additional delays induced by elevated traffic. For a more tightly coupled integration with a modern TSN scheduler (and an improved implementation of transmission graphs), you may want to look at our integration with FIPS.

This repository is part of the paper An (m, k)-firm Elevation Policy for Weakly Hard Real-Time in Converged 5G-TSN Networks. For more context please refer to this document: https://doi.org/10.5281/zenodo.19224732

TODO add reference to our paper

• Boost: used to build our shuffle graphs
• nlohmann_json: used to read input data.
