A&AI Instance Model Structure for E2E Network Slicing Case
Overview
E2E Network Slicing implements CSMF, NSMF and NSSMF in ONAP, in A&AI there has entities respectively corresponding to different instance management function.
...
The overall E2E Network Slicing A&AI instance model photo is:
Papyrus Diagram and ONAP AAI object mapping is:
Note: only when option 1, there will have self-nested cycles for RAN slice profile instance and RAN NSSI.
The whole design time Modeling framework can be found at Modeling enhancements.
New feature in
...
R7
In Guilin release, there has 3 new features:
- Transport Slicing models, details please refer and 3 subnet connection endpoint
- Add completed Slice profile service instance(changing node SliceProfile relationship from NSSI to sevice instance object)
- Have resource level Add underlay resources associations with NSSI
Transport Network Slicing Model
Overview
Transport Slicing model is part of the E2E Nerwork Slicing Modeling Structure, which will be used and maintained by TN NSSMF at Management and Control Plane level. Transport Slicing model will be mapped to TN Network reosurce model- CCVPN Model. Transport Slicing model refers IETF specification draft-rokui-5g-transport-slice-00.pdf.
Details of how to map to CCVPN Network model can be found at:
