Description

PNF Software upgrade includes:

  1. Support in-place software upgrade for PNF.
  2. Define generic building blocks, which can be used for workflow design in the design time.
  3. Support External Controller (e.g., EMS) as the main entity responsible for carrying out the detailed vendor-specific software upgrade steps.
  4. Enhance precheck and postcheck steps in the upgrade process by vendor-specific rules. Define procedures involved in the design time and run time for specifying these rules. 
  5. Enhance PNF modeling needed for PNF software upgrades (e.g., expected software version) and define processes in ONAP components (e.g., SO, A&AI, DCAE, and ONAP Controllers) for successful/unsuccessful software upgrades. 
  6. Demonstrate single PNF upgrade and batch upgrade.

PNF Software upgrade flow to be tested for Casablanca:

Bold items on the right will be tested (steps 6, 7, 10, 12, 14, 15).




Overall Process for Casablanca:

  • PNF upgrade process in Casablanca will follow the similar procedures used for VNF in-place upgrade in Beijing. Main differences:
    • Extended payload parameters for PNF in NB API for SDNC (e.g., PNF Identifier, PNF specific rules, External Controller info) 
    • PNF specific DG branches that are processed based on the presence of PNF specific parameters
    • Ansible adaptor that accepts External Controller end point as a parameter from API calls on interface 6.
    • External controller that executes commands received from ansible adaptor.
