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

New component capabilities for Dublin, 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


 Platform enhancements

  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

Update VF-C Northbound APIs to align SOL005. 

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.

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

Reference to the interfaces

VF-C R4 API Update

What are the system limits

Now the component Redundancy and scaling depends on Kubernetes.

Involved use cases, architectural capabilities or functional requirements

  1. Use case support

    1. CCVPN Use Case (Dublin)
    2. Use Case: Residential Broadband vCPE (Approved)
    3. Use Case: vFW/vDNS (Approved)

  2. Functional Requirements support 

      a. Centralized Representation and Consistent Identification of Cloud Regions In ONAP

      b. Hardware Platform Enablement In ONAP

Platform Maturity Targets

  • CII Badge silver is the stretch goal (lack resource)
  • 55% code coverage, all repos have already passed 

Listing of new or impacted models used by the project (for information only)

    Support for service/VNF DM and align with the above data model proposed by the modelling subcommittee in Dublin release

  • No labels
