- A new API needs to be developed, which takes the source and destination nodeId or TP's of a OTN network as input and finds the optimistic route between them.
- SDNC invokes this REST API to get the path for the given TP’s.
- The API performs the following operation:
- Reads the discover network information from AAI.
- prepare the discovery information according to the OOF model structure.
- push the model information to the mini zinc framework.
- get the optimistic route list from the framework.
- respond back to sdnc.
