L3AF Integration with 5G-UPF (User Plane Function)

By May 1, 2023January 28th, 2026Blog

L3AF introduces a comprehensive UPF architecture with support for hooks through AF_XDP. This allows developers to integrate custom multiple eBPF programs to enhance packet processing capabilities, offering greater control and flexibility in handling network traffic.

The L3AF approach brings several advantages; it enables developers to create multiple eBPF programs to enhance UPF functionality, resulting in efficient packet processing and improved network performance. Additionally, L3AF provides horizontal and vertical scaling options, allowing the deployment of multiple UPFs with multiple eBPF programs.

A Proof of Concept, lead by NgKore, demonstrates the Integration of L3AF with 5G-UPF (User Plane Function)
