Step 7 - Optimization to be done based on considering the following points : 

NSI Selection:

  1. Find the configuration requested for the NSI for the current request from AAI ( Fetch Service Profile)
  2. Find the difference between the response from DCAE and the requested config for the NSI (maxNoOfConnections in DCAEResponse – MaxNoOFPDUSessions in ServiceProfile)
  3. If the difference is > 0, allow for NSI reuse

RAN NSSI Selection:

  1. Find the configuration requested for the RAN NSSI for the current request from AAI ( Fetch AN Slice Profile)
  2. Find the difference between the response from DCAE and the requested config for the RAN NSSI
  3. If the difference is > 0, allow for RAN NSSI reuse
  4. For the moment, we can assume that the calculation for TN-FH and TN-MH slices returns true by default. But keep a place holder to do all these findings for TN-FH and TN-MH slices. We can enhance it later.

RAN NF NSSI Selection:

  1. Find the configuration requested for the RAN NF NSSI for the current request from AAI ( Fetch AN NF Slice Profile)
  2. Find the difference between the response from DCAE and the requested config for the RAN NF NSSI
  3. If the difference is > 0, allow for RAN NF NSSI reuse
