| OOFE-4 | Route Optimization | Provides an interface for Router Optimization and inter-domain route optimization. | https://docs.onap.org/projects/onap-optf-osdf/en/latest/sections/offeredapis.html Inter-domain swagger Reference (This review will show the added new API. This can also be found under the docs above) |
| OOFE-5 | OOF Model Administrator | This is for the OOF Model Administrator API. This API is a way to dynamically change the optimization models that will be used to find solutions for various optimization problems. This API will be used to Create, Update, or Delete Models. | |
| OOFE-6 | This interface enables slice selection recommendations (NST, NSI, NSSI, Slice Profiles), as well as slice termination recommendations (NSI, NSSI). | https://docs.onap.org/projects/onap-optf-osdf/en/latest/sections/offeredapis.html Slicing swagger reference (This review will show the changes done to the API. This can also be found under the docs above) |
