Project Overview
VF-C leverages ETSI NFV MANO architecture and information model as a reference, and implements full life cycle management and FCAPS of VNF and NS.
- support NS and VNF lifecycle management based on the ONAP tosca data model and workflow
- support integration with multi VNFMs via drivers, which include vendors VNFM and generic VNFM
- support integration with multi VNFs via generic VNFM, which does not provide VNFM function
- support integration with multi VIMS via Multi-VIM, which include the opensource and commercial VIMs
- support microservice architecture and model driven orchestration and management
VF-C has two main components: - NFV-O Component,
- GVNFM ComponentThere is no scope and architecture changes for VF-C in Dublin release.
For a more detailed overview - https://wiki.onap.org/pages/viewpage.action?pageId=3247130
Architecture changes from E release:
VF-C catalog migrate to modeling etsicatalog repo which has reported in Architecture meeting 2019-10-15
Modeling project has created etsicatalog repo to intent to provide common ETSI catalog service, VF-C catalog migrates to modeling can help reduce duplication of work and promote unified architecture.
Migration plan:
- VF-C catalog migrates to modeling etsicatalog repo and merges with modeling existing etsicatalog parser service and package management service.
- To ensure compatibility, the APIs provided keep the same after migration , VF-C/UUI promises to update their interfaces call if needed.
- In F release, new requirements will be implemented in modeling etsicatalog , VF-C catalog is no longer maintained.
New component capabilities for Frankfurt, i.e. the functional enhancements
...
Functional enhancements
1. VF-C enhancement and new features:
2. Python upgrade from python2 to python3
3. JDK upgrade evaluate and migrate (Depend on the commit resource)
4. VF-C integrate with CLI to improve VF-C Usability
5. Improve GVNFM Driver as SOL003 adapter 6. Provide 2. Implement python-based Dmaap library to subscribe other components topics
73. Supporting LCM Operation rollback(Stretch goal)
8. Add 4. working with Integration team to add VF-C related use case vCPE on daily CI chains
...
Platform enhancements
1. Upgrade all python component from python2 to python3
2. Improving platform maturity : Mariadb-Galera DB Consolidation ,security (i.e., S3P items)
23. Supporting use cases identified by ONAP and integration: vCPE
34. Supporting Functional Requirements identified:
ETSI Alignment : migrate VF-C catalog to modeling etsicatalog
E2E Network Slicing: (supporting NSSMF,Stretch goal depend on the commit resource )
New or modified interfaces
Update Remove Catalog interfaces from VF-C Northbound APIs to align SOL005. currently interfaces
If they are modified, are the backwards compatible?
Yes, almost APIs required parameters has been supported by previous version,the alignment will add more optional parameter support which can comply with previous APIs. Remove the catalog interface will not affect the existing APIs, so they are backwards compatible
Interface naming
VF-C supports the following APIs:
- NSLCM APIs (Create/Instantiate/terminate/delete/scale/heal....), such as
api/nslcm/v1/ns
Package management APIs( VNF/PNF/NS package create/upload/delete/update ....), such as
api/nslcm/v1/ns/(?P<ns_instance_id>[0-9a-zA-Z_-]+)/instantiate
api/nslcm/v1/subscriptions
api/nslcm/v1/ns_lcm_op_occs
api/vnfpkgm/v1/vnf_packages api/vnfpkgm/v1/subscriptions
Reference to the interfaces

Use case support
Use Case: Residential Broadband vCPE (Approved)Functional Requirements support
...
b. LCM(instantiate/terminate/heal/scaling) for NS and Vendor VNFs
c. FCAPS for vendor VNFs
d. LCM(instantiate/terminate) for open source VNFs
e. Minimum VF-C components supporting above functionalities:
f. NSLCM/GVNFM/Workflow/Vimproxy/EMS driver/vendor VNFM driver
