- Find the configuration requested for the RAN NF NSSI for the current request from AAI ( Fetch AN NF Slice Profile)
- Find the difference between the response from DCAE and the requested config for the RAN NF NSSI
- If the difference is > 0, allow for RAN NF NSSI reuse
The optimization method to be done depends on the feasibility of the below two suggested methods :
1 - Including the operator attribute in the constraint model of the HAS template to find the current throughput
2 - Passing only the difference attribute ( current throughput) to the constraint model of the existing HAS template
