This is a continuation of the use case started in Casablanca: 5G - PNF Software Update

Background (R3 Casablanca)

In Casablanca,  the UC leveraged the Ansible adaptor of ONAP controller to implement three S/W upgrade related operations for 5G PNFs. As an important feature the new workflow supports an External Controller (EC) in the execution of these operations. All these operations  have shared the same LCM APIs with VNF S/W upgrade with PNF specific parameters passed in the API payloads. The corresponding DGs of LCM APIs are updated. The operations are:

  • /operations/LCM:upgrade-pre-check
  • /operations/LCM:upgrade-software
  • /operations/LCM:upgrade-post-check

Dublin Scope

For Dublin, the target of this UC includes:

  • 3GPP Software Management API alignment
    • Extend upgrade-software operation by leveraging sub-operations from 3GPP (like download/install/activate).
    • Rollback/fallback API support for 5G PNF
  • Introduction of an upgrade option based on direct NETCONF interface between the ONAP controller and the PNF/EMS (Moved to El Alto)
  • rollback operation support for PNF (considering VNF as well).
  • e2e bpmn workflow support for PNF in-place S/W upgrade
  • VF-C support  for PNF in-place S/W upgrade??
  • hardcode removal
  • ......

Other areas include VID/UUI and SO for re-usable high-level SW upgrade workflows.

  1. Support vendor-specific mapping of upgrade APIs to NETCONF requests in addition to other options.

  2. Support of roll-back API for PNF, New DG needed. Impact to SO building blocks.
  3. change to existing APIs
  4. API payload (no effect on DG processing), parameters used by playbooks.
  5. playbooks update. (Distributed with source-code)
  6. No impact to SDNC code.
  7. R4: Rollback API support for xNF
  8. API and playbook enhancements for S/W upgrade based on 3GPP S/W management API enhanements
  9. PNF S/W upgrade workflow design and test (Stretch goal)
