Overview:

The PNF software upgrade use case consists of three main parts:

  • SDC for distributing the resource model and custom workflow design
  • SO will implement building blocks in workflow for preCheck, downloadNeSw, activateNesW, updateAAI & postCheck.
  • CDS Blueprint Processor will implement the mount, configure and un-mount requests to SDNC/ODL. The processor currently has the ability to read a blueprint from archive and process it.

JIRAs:

TODO - Need to create a filter to link all JIRAs


Deployment:

Test environment requirements for the test cases:

  • xNF simulator for test cases:  PNF Simulator with TLS & YANG support.
  • Rest Client simulator.
  • SO with BB implemented in workflows.
  • CDS Blueprint processor enhanced so that it can send mount, send configuration and un-mount rest request to SDNC.

This environment can be set up by following the steps below.

  1. Repo : Yet to update
  2. RUN : Yet to update

Use Case preconditions:

    • xNF simulator.
    • Rest Client sim.
