All these endpoints are required as an input to TN NSSMF to create the logical links that denotes back-haul, front-haul and mid-haul interfaces. Endpoint consists of IPAddress, logicInterfaceID and nexthopinfo.

Note:

1a.  Core, RAN endpoints for back haul are manually entered in UUI and other RAN nodes endpoints for FH and MH are predefined values in the previous releases.

2b.  RAN endpoint for back haul will be covered in this release

3c. Core endpoint, FH and MH endpoints are stretch goal

General Information:

RAN and Core NF's IP addresses are assigned as below:

  • If the NFs are deployed as VNFs, VNFM takes care of the IP address assignment
  • If the NFs are deployed as CNFs, Kubernetes assigns a unique IP address to the pod. If it is a single container, docker daemon itself acts as a DHCP server and assigns an IP address to the container.

In both the above cases, assigning an IP address is taken care by the cloud provider itself.

In Core Slicing, netbox-ip-assign microservice is used by SDNC to assign IP address to the VF modules and VNFs. But this is not used effectively by CDS and the multicloud. Kubernetes itself assigns the IP address, moreover assigning a static IP is not a best practice in Kubernetes.

IP Address:

More than one CUCP gateway IP ( where NFs are deployed) can be applicable and can be configured for a slice.
