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
    • South-bound of SDNC: Extend upgrade-software operation by leveraging sub-operations from 3GPP (like download/install/activate).
    • North-bound of SDNC: Rollback/fallback API support for 5G PNF
  • Workflow support for PNF in-place SW upgrade in SO (stretch goal)

  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 and SDNC.
  3. LCM API payload  and playbook enhancements for S/W upgrade for alignment with 3GPP S/W management APIs in ansible playbooks
  4. PNF S/W upgrade workflow design and test (Stretch goal)

API changes

  • New LCM:upgrade-rollback API for SDNC
  • Possible payload changes into existing API /operations/LCM:upgrade-software
  • sw download, install and activate APIs in southbound of SDNC (to EC) as part of Ansible playbook for LCM:upgrade-software API.
