This demo shows a 5G X-haul testbed enhanced with P4 switches implementing the offloading of the User Plane Function module. The P4 code includes GTP protocol encapsulation/decapsulation function, fully configurable N3-N6-N9 steering, and advanced online monitoring of the experienced latency metadata.
