Borrowing some initial material from Use case proposal: 5G- RAN deployment, Slicing, SON

Homing plays a key role in the 5G RAN Deployment:

Disaggregated 5G RAN consists of hybrid network elements (PNF and VNF) and will require a cloud infrastructure deployment at the edge. SDC would define the models for the 5G VNF and PNF resources. On receiving service instantiation request via Portal or external API, SO will decompose the request, and call HAS to find optimal placements for the VNFs. HAS would query AAI, and MultiCloud to identify available resources, and provide optimal placement for the RAN components. The design parameters needed for use by HAS for placement of 5G VNF resources would be available from SDC, and the policies that guide the placement would be provided by the policy framework. The workflows are envisioned to be similar to the vCPE Use Case.
