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 Component
    There 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 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  •  In F release, new requirements will be implemented in modeling etsicatalog , VF-C catalog is no longer maintained.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. OOF Integration Optimization
    Optimize the methodology for VNF(vdu) placement, add the process for placement with selected candidates(VIM)
  2. SOL005 Interface alignment
    a. existing APIs alignment
    b. add the APIs which supported in SOL005, such as package subscription and notification
  3. Upgrade Mutlicloud API invocation to support Centralized Representation and Consistent Identification of Cloud Region functional requirement

...

  1. Mysql DB migrates to OOM shared MariaDB Galera Cluster which can be used to meet S3P HA requirements.

    1. Update VF-C DB Helm Chart
    2. Update VF-C component to leverage new MariaDB Galera Cluster 
      1. Docker configuration update 
      2. DB script migrate 
      3. Other work 
  2. Configuration Improvement
    1. Investigate all VF-C configuration could be automatically injected through OOM.
  3. Data Persistence
    Add data persistent storage to avoid data loss due to pod restart

New or modified interfaces

...

      1. VF-C integrate with CLI to improve VF-C Usability

      2. Implement python-based Dmaap library to subscribe other components  topics

      3. Supporting LCM Operation rollback(Stretch goal)

      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)

    3. TSC must have items

  • Document current upgrade component strategy(TSC must have)  Image AddedVFC-1576 - Document current upgrade component strategy(TSC must have) OPEN

  • SECCOM Perform Software Composition Analysis - Vulnerability tables(TSC must have) - plan to solve the most of the security issues, but also depends on the commit resource  Image AddedVFC-1574 - SECCOM Perform Software Composition Analysis - Vulnerability tables(TSC must havve) OPEN

  • SECCOM HTTPS communication vs. HTTP(TSC must have) - Based on the resource contribution  Image AddedVFC-1577 - SECCOM HTTPS communication vs. HTTP(TSC must havve) OPEN

New or modified interfaces

Remove Catalog interfaces from VF-C 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:

  1.  NSLCM APIs (Create/Instantiate/terminate/delete/scale/heal....), such as 

    api/nslcm/v1/ns
    api/nslcm/v1/ns/(?P<ns_instance_id>[0-9a-zA-Z_-]+)/instantiate
    api/nslcm/v1/subscriptions
    api/nslcm/v1/ns_lcm_op_occs

  2.   Package management APIs( VNF/PNF/NS package create/upload/delete/update ....), such as 
     api/vnfpkgm/v1/vnf_packages
     api/vnfpkgm/v1/subscriptions
