In Honolulu, we can consider 2 cloud instances (one edge DC and one regional DC), and based on the Slice Profile, we could consider Core NF placement - e.g., for a URLLC slice (low latency), we could place UPF in the edge DC.Pre-condition: It has been decided by Core NSSMF
| Scenario | Action(s) | Scope in Honolulu |
|---|---|---|
| Core NSSMF has decided to instantiate a new Core NSSI. All Core NFs have to be instantiated newly | OOF will be triggered for determining the Core NF placement | Intent is to cover this (see details below table) |
| Core NSSMF has decided to instantiate a new Core NSSI. Some Core NFs have to be instantiated newly (e.g. |

| , UPF), while others shall be reused (e.g., AMF) - this is determined by examining the shareability of Core NFs and feasibility to support the new NSSI (based on capacity/resource occupancy levels/scaleability). | OOF will be triggered for determining the Core NF placement for the new Core NFs. In case of scaling any existing Core NF, OOF shall be triggered for placement of new instance. (Note: This also has implications in Modeling of Core NS, and resourceSharingLevel of Core NSSI) | Out of scope |
| Core NSSMF has decided to reuse an existing Core NSSI. All Core NFs shall be reused, without scaling. | No impact. | Covered |
| Core NSSMF has decided to reuse an existing Core NSSI. All Core NFs shall be reused, one or more with scaling. | OOF shall be triggered for placement of new instance. | Out of scope |
| Core NSSMF has decided to reuse an existing Core NSSI with modifications. Some Core NFs shall be reused (with/without scaling) while others have to be instantiated newly or selected from those serving other NSSIs. | OOF will be triggered for determining the Core NF placement for the new Core NFs. In case of scaling any existing Core NF, OOF shall be triggered for placement of new instance. For selecting Core NFs serving other NSSIs, OOF may be triggered considering placement also.
