Research on evaluation model and technology of 5G core network User Plane Function

The development of the market and standards highlights the importance of the 5G core network User Plane Function, and brings a variety of types of equipment. In order to explore the unpredictable actual performance of the equipment in the existing network, we propose an evaluation model based on the existing network, including a system architecture that simulates the deployment architecture of the existing network and a service traffic model based on the actual business status of the existing network. We study two devices using different technologies based on this model. The results show that the traffic forwarding delays of several services are different, and the forwarding delay of UDP traffic is the lowest. And the Smart NIC brings great benefits to the device performance. The forwarding delay of several services traffic is optimized to different degrees, the HTTP Streaming's is reduced by 33%, and the UDP's is reduced by 70%.
