E2E Model structure optimization
- New/Enhanced features
- Introduce Slice Profile Templates to carry user slicing subnet requirements, in ONAP we have 3 kinds of Slice Profile Templates, for RAN, Core and CN separately.
- Add RAN NSST and TN NSST to support RAN and TN NSSI deployment, in TN side, also add TN Network Requirement Template to support TN connection links creation.
- Has allotted resource relationship between slice subnet requirements and subnet slice resource, see 1, 2, 3. Allotted resource
- 4 is inner TN, between subnet resource and logical network resource.
- Update relationship between NST and NSST using allotted resource, instead of nested, see 5.
- Supprting Suooprting for both option 1 and option 2
ONAP option 1 and 2 differs on the RAN and FH/BH relationship, in option 1, RAN NSSMF will decide FH/MH requirements and send to TN side, so RAN NSST will nest FH/MH NSST, and slice profile requirements will contain not only RAN side requirements but also FH/MH. In option 2, FH and MH are independent requirments when doing E2E requirements decomposition. Detailed background of option 1 and 2, please see E2E Network Slicing Use Case in R7 Guilin.
