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.
- Repo : Yet to update
- RUN : Yet to update
Use Case preconditions:
- xNF simulator.
- Rest Client sim.
Upgrade One PNF Instance
