Scope

PNF software upgrade is one aspect of Software Management. The purpose of this procedure is to upgrade the software currently running on the PNF to a target software version without impacts on PNF schema and service template. The details of the solution including: 

  • Enhancement and additions of PNF in-place software update.
  • Support direct PNF NETCONF interface with the vendor-specific YANG model.
  • Enhance SO in-place software upgrade workflow with generic SO building blocks, which can be used for workflow design in the design time.
  • Using CDS self-service API between SO and controller with the support of PNF in-place software upgrade
  • Enhance VID to demonstrate single PNF in-place software upgrade
  • Enhance SO procedure to support AAI update after the software upgrade completion.

Procedure

Pre-conditions

  • ONAP is ready to use
  • SO upgrade workflows are ready to use
  • A SDC service template with one PNF resource is designed (including CBA association) and it is distributed to run time
  • Service instantiation is completed, including PNF PnP. meaning a PNF instance is in operation with connectivity between PNF-ONAP, PNF-SFTP​

Upgrade Procedure

1.Vendor delivers the new software image to the operator and stored in the SFTP server

2.At the VID, operator

  • selects a work-flow, and a PNF instance,
  • provides the target software version, and
  • initiates the upgrade procedure

3.SO executes the workflow

a) SO sends CDS request(s) with action-identifier {actionName, blueprintName, blueprintVersion} to the blueprint processor inside the controller using CDS self-service API

b) Controller/blueprint processor executes the blueprint scripts including sending Netconf request(s) to the PNF instance

c) SO updates the A&AI with the active software-version when the upgrade is completed
