Summary: Edge Scoping
...
- Cloud SW Capability example
- Cloud region "x" with SR-IOV, GPU, Min-guarantee support
- Cloud region "y" with SR-IOV support
- Cloud HW Capability example
- Resource cluster "xa" in Cloud region "x" with SR-IOV and GPU support
- Resource cluster "xb" in Cloud region "x" with GPU support
- Resource cluster "ya" in Cloud region "y" with SR-IOV support
Note 3:
- 5G Service/VNF placement example
- Constraints used by Optimization Framework (OOF)
5G CU-UP VNF location to be fixed to a specific physical DC based on 5G DU, bounded by a max distance from 5G DU
- Optimization Policy used by OOF
Choose optimized cloud region (or instance) for the placement of 5G CU UP for subscriber group based on the above constraints
- Constraints used by Optimization Framework (OOF)
Note 4:
- For the 5G Service/VNF placement example in Note 3
- 5G CU-UP VNF preferably maps to a specific Cloud region & Physical DC End Point
Note 5:
- For the 5G Service/VNF placement example in Note 3
- OOF will pass the Physical DC End Point to SO as a opaque data
Note 6:
- For the 5G Service/VNF placement example in Note 3
- SO passes the Physical DC End Point to Multi-Cloud as a opaque data, besides the Cloud Region
