Architecture

This section describes how the network function components interact when the multiple VIP model is implemented.

The multiple VIP architecture focuses on high availability and load-balancing aspect of IP addresses in 5G. With relevance to the multiple VIP graphic, the Policy Engine invokes a new rest-ep service for a NF when you assign an IP address as an external endpoint. All the incoming requests from the network functions, such as NRF and SMF are routed to the rest-ep-service and the traffic is redirected to the pcf-rest-ep pod. The pod has a bilateral communication with the PCF Engine. The rest-ep-service operates as a load balancer.
