Experience
In-kernel Solution Based on BPF/XDP for 5G UPF
https://github.com/navarrothiago/upf-bpfIt stands on three foundational pillars:
• In-kernel fast packet processing.
• Highly flexible and programmable data plane.
• Portable to different systems.
Currently, the project is transitioning to integrate with the OpenAirInterface (OAI) 5G UPF, marking a significant step forward in its development.
