Behavior Change

Previous Behavior: UDP proxy was used as endpoint for PFCP and GTPC messages. With minimal packet processing, the UDP proxy was forwarding the messages to the GTPC-EP pod; the surge of messages could lead to packet drop.

New Behavior: Protocol pod is used as the endpoint for PFCP messages. GTPC-EP pod is used as the endpoint for GTPC messages. The UDP proxy bypass improves the CPU usage by reducing one hop across microservices in the signalling path.

Customer Impact: No impact.
