- Model and policy driven application controller with intrinsic VNF management capabilities.
- Support of multi vendor system of VNFs with interdependence between them.
- Provide uploading capabilities of standard data model which describe the management, configuration and inter-dependencies of the VNF.
- APPC model will be based on ONAP TOSCA and Yang containing a dependency model, LCM recipes, configuration templates, policies etc.
- APPC provides multi-protocol southbound plugins, including support for NETCONF, Chef via a Chef Server, and Ansible and ability to operate through vendor specific VNFM/EMS via adaptation through a plugin.
- APPC provides a VNF configuration repository with the latest working configuration for each managed VNF instance it is responsible for.
Scope
Support for complex ONAP use cases including vVOLTE (with vEPC) and vCPE
Provide Generic VNF LCM commands for Northbound consumers (SO, Policy, CMO, DCAE, etc.)
The implementation of LCM commands will use an uploaded VNFD TOSCA model to infer an execution protocol and drive workflows
Design-time ability to attach recipes (specified by Directed Graphs, aka DGs) to specific VNF LCM commands, or "Actions" received via the Northbound APIs.
Provide a model driven configuration API composed from a Yang-based VNF configuration model and set of templates to map payloads to the VNF configuration protocol.
Provide configuration repository APIs getLatestConfig, configAudit etc.
Manage the VNF operational state including Blocking, Sequencing and Session Throttling
Provide conflict resolution for multiple LCM requests
Provide flexible deployment options such as HA, single node or geo-distributed deployment
Adaptation of additional NBI definitions established by ETSI-MANO using NFV-O to leverage existing APPC functions which already exist, including:
Scale VNF
Terminate VNF
Query VNF
Operate VNF
Modify VNF Information
Get Operation
Status
Adaptation of NBI definition at the orchestration level by invoking existing orchestrator functions, including:
Create VNF Identifier
- Delete VNF Identifier
- Instantiate VNF
- Build additional DGs to implement new ETSI defined NB APIs not currently supported by APPC
- Scale VNF to Level
- Change VNF Flavour
- Heal VNF
- Support for GVNFM functionality through additional SB adapters to support:
- Bridging to a compliant S-VNFM when this functionality is provided by the VNF
- Utilize ETSI VNFD acquired from a VNF to define the configuration and management data model of the VNF.
Proposed Architecture:
Architecture Alignment:
- How does this project fit into the rest of the ONAP Architecture?
- Expansion of existing APPC ONAP component to support more complex use cases.
- Establish dependence on the SDNC framework (aka Controller framework) Common Controller SDK to be used as the base platform for the controller.
- Depends on Service Designer for generating the model(s) and other artifacts necessary for specifying controller runtime behavior
- Depends on Multi VIM project for cloud infrastructure APIs
- How does this align with external standards/specifications?
- Inspired by ETSI NFV LCM signatures
- Use TOSCA and YANG for all model definitions.
- Use Netconf/Chef and Ansible for component southbound interface
