IPAM Integration

The IPAM and SMF reside in the Application Services layer.

  • SMF Node Manager Application—The SMF Node Manager application handles the UPF, ID resource, and IP address management. Hence, the SMF Node Manager application integrates IPAM cache and IPAM client modules. The UPF manager uses the IPAM client module for address range reservation per UPF.

  • SMF Service Application— The SMF Service application provides PDU session services. During session establishment and termination, the IP addresses are requested and released back. The SMF Service application invokes the IPC to Resource Manager (RMGR) in Node Manager, which receives (free) the IP from the IPAM module.

  • IPAM Server Application—Based on the deployment model, the IPAM Server application can run as an independent microservice, as a part of the same cluster, or in a remote cluster. For standalone deployments, the IPAM Servers are an integral part of the IPAM cache.
