P4 GNN - General GNN processing on PDPs

This repository contains the tools to implement a generic GNN processing pipeline on a P4-driven data plane. It contains:

• A P4 Code Generator that creates a .p4 file which implements a given GNN model.
• A Verify Program that runs GNN classification of a given model to compare with the data plane results.
• An Installation Script for Ubuntu 20.04 (adapted from the P4 Tutorial).
• A Dockerfile to install the system in a container for easy reproducibility.
