For Casablance release, we propose the following functionalities.
1) Flexible workflow designer and orchestrator
- Impacted components: SDC, SO, VID
- Contributors: AT&T, Amdocs, Huawei (?)
- Functionalities
- Catalog in SDC for meta-data about the building blocks – completed by Amdocs
- Designer/editor in SDC for creating workflow – committed to develop by Amdocs
- Convert already existing building blocks/activities to be workflow designer ready
- Move workflow out of service model to independent artifact – priority nice to have
- Distribution of workflow to SO – preferably with workflow as independent artifact
- Deployment of workflow in SO
- User interface (VID) to select workflow and input parameters for execution
- Execute workflow in SO
- Rainy day handling for unsuccessful workflow steps
- Visualize the execution results on VID dashboard
- Ability to cancel workflow execution (VID)
2) Traffic migration building block
- Impacted components: SDNC, APPC, VFC, SO
- Contributors: AT&T, Orange, Intel
- Functionalities
- Common API definition for traffic migration
- Use case across different VNF types – vGW/vCPE, vFW, vLB, vDNS, vVOLTE (will need to pick/prioritize)
- Assessment report on commonalities/differences across VNF types – e.g., IP based redirection, DNS based or load balancer
- Incorporate recipe for traffic migration as part of in-place software upgrade workflow – quiesece/resume traffic are part of the SO workflow
- Develop recipe (using Ansible, NETCONF or REST) for traffic migration depending on the protocol used to communicate with the VNF
3) 5G RAN PNF Software upgrade
- Impacted components: APPC, SO, SDC, A&AI, Ansible/EM
- Contributors: AT&T, China Mobile, Huawei
- Functionalities
- Leverage in-place software upgrade Beijing use case to demonstrate application to 5G RAN PNFs
- Health check (pre/post)
- Software download, installation and activation
- Roll-back for unsuccessful execution
- Manual processing / intervention for failures/roll-back issues
