xApp Development from Zero to Hero: Online Resources

This repository provides online resources to support xApp development for managing O-RAN networks. It provides xApp developers with example configuration files, source code for xApps in Python, representation of ASN.1 data structures in Python, and a cheat sheet of useful commands.

Please see the repository structure below:

1. Example configuration files (xApp descriptor, schema, static RMR route file, and Dockerfile)
2. Example source codes (including both RMRXApp and XApp implementations)
3. Python representations of ASN.1 (from the E2AP, E2SM, and KPM specifications)
4. Command cheatsheet (for Docker, Kubernetes, and dms_cli to interface with the AppMgr)

Each link provides additional information about the specific resources.

This repository serves as a companion to our tutorial paper:

Joao F. Santos, Alexandre Huff, Daniel Campos, Kleber V. Cardoso, Cristiano B. Both, and Luiz A. DaSilva, “Managing O-RAN Networks: xApp Development from Zero to Hero”, publicly available on arXiv preprint arXiv:2407.09619, 2024.

For more information and context about this repository and the online resources therein, check our preprint manuscript on ArXiv: https://arxiv.org/abs/2407.09619.

Note that we leverage the Python xApp Framework from the O-RAN Software Community to develop xApps. For more information about it, please check its official documentation. In addition, we leverage PyCrate to create the representations of ASN.1 in Python. For information and examples about it, please check its official repository.
