Project Name:
- Proposed name for the project: Network Function Change Management
- Proposed name for the repository: NFCM
Project description:
- Network Functions (NFs) like any software have to be updated periodically (to support new features, fix bugs, security holes, etc). However, complex dependencies, upgrade mechanisms, SLAs etc require that the upgrades or changes are managed carefully. For example, NFs may by upgraded in-place or through a scale out and replace mechanism. The change may require draining, redirection, or load-balancing of traffic. It may also involve multiple NFs whose changes need to be coordinated for service continuity. It will also require capabilities like A/B testing, pre- and post- change testing, scheduling, etc. This project, Network Function Change management, provides the capability to design, schedule and manage configuration changes and software upgrades of network functions managed by ONAP. This project exposes the existing capabilities of ONAP components (like that of the service orchestrator and the controller) to users to help them stitch workflows that use these capabilities for managing NF changes or upgrades.
Scope:
- This project provides users with the ability to design workflows based on a suite of existing capabilities exposed by other ONAP components. For example, a user can make calls to a controller to execute actions, to A&AI to get inventory status, and existing orchestration flows, and combine these calls to achieve a higher level orchestration function. We envision that this design capability will get integrated with the SD&C environment.
- This project provides a capability to deploy (and undeploy) and upgrade the designed workflows to an execution environment (e.g., the service orchestrator). This assumes that the execution environment provides APIs to perform these functions.
- This project provides runtime management (start, pause, resume, stop, rollback) and monitoring of the workflows. This project provides a portal for a user to come in and manually control these workflows or monitor them. Again we assume that the execution environment provides APIs to perform these functions. We also assume that other ONAP components (e.g., Policy) can trigger one of these workflows as part of a control loop action.
- This project provides capabilities for scheduling workflows. The schedule could range across a subset of the instances of an NF, across instances of multiple NFs or combinations therein.
- This project provides capabilities for selecting the type and instances of the NFs that need to be associated with the workflows (as well as for scheduling).
- The project will provide capabilities for tracking the history of workflows that have been executed.
- This project will document the best practices for End-to-End workflow design.
