CNF Support Architecture

The following diagram depicts ETSI-based CNF support Architecture.



CNF Support

  • CNF Support is one of Ericsson’s highest priority work items for ONAP

    • Define a fast path to CNF support, and accomplish it across multiple releases (Honolulu+)

    • For now, leverage currently available ETSI Stage 2 specifications, without just waiting for ETSI Stage 3 (SOL)

  • Many (Ericsson, Verizon, Bell Canada, Huawei, others) believe the target is CNF, 5G Edge, etc. VNF support is a steppingstone towards that goal

  • CNF support and Cloud Native Support are closely related.

    • CNF enables Cloud Native (Microservices, Containers, Elastic scalability, On-demand deployment)

    • What other Cloud Native support?  APs: Define its scope and study architecture

    • In Honolulu, CNF scope is:

      1. CNF modeling and distribution support for microservice-based CNF and images,

      2. CNF LCM through SO, SO NFVO (or VFC) and VNFM via standard APIs (covering instantiation and Day 0 configuration based on Helm Charts)

        1. Note: VNFM support for CNF is vendor-specific

      3. OOF-based Granting only for both VNF/CNF Instantiation and Termination, not for VNF/CNF Healing or Scaling

      4. Software Images and Container Image Handlings via NFVO, ETSI Catalog Manager and CIR

      5. Collaborate with non-ETSI-based CNF support in SO; SO launches the CNF LCM path based on models (i.e., model-driven)



Configuration Support Architecture

This following diagram depicts ETSI-based Configuration support.



  • Leverage CBA design and SDC distribution (CBA + CSAR) for model-driven configuration

  • Leverage existing CDS, SDNC / MultiCloud path, or new ETSI-based configuration support thru Ve-Vnfm (SOL002)
