ONAP Controller Family (SDN-C / App-C) configures and maintains the health ofL1-7 Network Function (VNF, PNF, CNFs) and network services throughout their lifecycle
- Configure Network Functions (VNF/PNF)
- Provides programmable network application management platform:
- Behavior patterns programmed via models and policies
- Standards based models &protocols for multi-vendor implementation
- Extensible SB adapters such as Netconf, Ansible, Rest API, etc.
- Operational control, version management, software updates, etc.
- Local source of truth
- Manages inventory within its scope
- Manages and stores state of NFs
- Supports Configuration Audits
2. SDN-C/APP-C API definitions
Controller provides the following interfaces:
| Interface Name | Interface Definition | Interface Capabilities |
|---|---|---|
| CONE-1 | Operations Interface | An interface to request for Lifecycle management operations on network resources |
| CONE-2 | OSS Interface | An interface to request for Lifecycle management operations on network resources |
| CONE-3 | Service Order Interface | An interface to request for Configuration and Lifecycle management operations on network resources |
| CONE-4 | Policy Interface | An interface to support LCM requests such as Restart, Rebuild, Migrate, Evacuate operations on network resources (APP-C interfaces with openstack to send those LCM requests to VNF/VNF-C/VM) |
