Cases and Status
| # | Test Case | Status | ||||||||
|---|---|---|---|---|---|---|---|---|---|---|
| 1 | Successful design of CST, Service Profile and Slice Profile Templates |
| ||||||||
| 2 | Successful design of NST, NSSTs (RAN, Core and Transport) |
| ||||||||
| 3 | Service instantiation via CSMF portal which involves RAN, Core and Transport sub-nets (RAN NSSMF within ONAP). It should result in a new NSI and new NSSIs to be created for all sub-nets. (Option 1) |
| 2 | |||||||
| 4 | Service instantiation via CSMF portal which involves RAN, Core and Transport sub-nets (RAN NSSMF outside ONAP). It should result in a new NSI and new NSSIs to be created for all sub-nets. (Option 2) |
| ||||||||
| 35 | Service instantiation via CSMF portal which involves RAN, Core and Transport sub-nets (RAN NSSMF within ONAP). It should result in a new NSI and new NSSIs existing NSSI to be created for all sub-nets.reused at least for 1 subnet. (Option 1) |
| ||||||||
| 6 | Service instantiation via CSMF portal which involves RAN, Core and Transport sub-nets (RAN NSSMF outside ONAP). It should result in | a new NSI and new NSSIs existing NSSI to be | created reused for | all RAN sub- | nets.net (Option 2) |
