Feature Description
You can now enable the IPv4 communication between PCF and the other network functions such as AF, SMF, NRF, CHF, and UDR through multiple virtual IP addresses (VIP). With a provision to configure discrete VIP addresses or external IP addresses for each rest-ep service and link them to an endpoint, you can prevent sharing of IP addresses between the NFs. Multiple VIPs take the role of a load balancer to offer a high availability environment.
In a scenario where multiple calls are simultaneously made to a distinct network function, the policy service spawns different REST ep services to complete each interaction. PCF spawns a service using the IP address available in the IP pool.
PCF supports both IPv4 and IPv6 connectivity on N5, N7, N28 and NNRF external interfaces/endpoints (inbound and outbound).
