  • SDC preserves the SOL004 VNF Packages in the Onboarded_Package directory of SDC Resource CSAR
  • SDC Service CSAR including SDC Resource CSAR(s) is distributed to ONAP Runtime components: SO, AAI, VID and others
  • ETSI Catalog Manager extracts the SOL004 VNF Packages and stores in its Database
  • If VNF Package contains Container Images, ETSI Catalog Manager pushes the images to Container Image Repository
  • <note: it is under discussion that ETSI Catalog Manager pushes the helm charts from the CSAR to a MANO local helm charts repository if we use the helm charts repository>
  • SOL003 Adapter gets SOL004 VNF packages from ETSI Catalog Manager
  • SOL003 Adapter sends SOL004 VNF packages to sVNFMs
  • Optionally, if operators use local CIRs, VNFM can push the Container Images to the local CIRs.
  • SVNFMs invokes K8S CISM for CNF operations
  • K8S CISM pulls Container Images from the CIR


CNF Orchestration Sequences

The following depicts the CNF Orchestration sequences.



CNF Models

  • Conforms to ETSI IFA 011, 029 and 040.
  • Those specifications would be available by end of June / July 2020, but their SOL specifications plan to be available by end of 2020 or Q1, 2021.
  • Until then, ONAP designs CNF models and packages, based on the current IFA 029 and 040 (it is an assumption).
  • A Managed Container Infrastructure Object (MCIO) is an abstract NFV object for OS Container management and orchestration.
  • The declarative MCIO descriptor is used as descriptor object interpreted by the CISM.
  • A MCIO is created by the CISM by allocating its requested infrastructure resources on Container Infrastructure Service (CIS) instances
  • Depending on its type, the creation of a MCIO may include the deployment of an OS Container Image.
  • MCIO’s are lifecycle managed via change requests on their desired state, utilizing a modified declarative descriptor sent to the CISM, which adapts the
  • infrastructure resource allocations according to the changed infrastructure resource requests.
  • MCIO’s requesting compute and/or storage infrastructure resources are modeled as a VNF Component (VNFC).
  • Properties of an MCIO described in declarative descriptors and relevant being exposed to NFV-MANO are mirrored in attributes of the descriptors of the corresponding objects of the existing NFV-MANO information model.
