This The use case (

...

• SDC supports SOL004 Package onboarding
• SDC supports SOL007 Design
  • SOL007 Onboarding is not yet supported in Honolulu
• ETSI Catalog Manager receives SDC Package notification
• ETSI Catalog Manager gets the original vendor ETSI NS and VNF packages and stores them into its database
• ETSI Catalog Manager sends the package onboarding notification to its subscribers (SO NFVO, SOL003 Adapter, in the future SOL005 Adapter)
• If the SOL004 VNF package embeds Container Images, ETSI Catalog Manager pushes the images to CIR via Docker Registry APIs
  • Currently, ETSI Catalog Manager defined this Container Image handling as a stretch goal goal
  • If not (due to SDC 2MB Image file size limitation), ETSI Catalog Manager does not handle Container Images. In that case, the operator will upload Container Image(s) to the CIR component directly
  • In this case, SOL004 Package metadata will references reference Container Image file(s)
• CIR will be realized by Nexus with Docker Registry (GitHub is under consideration)
  • CIR component can be delivered part of ONAP or the operator can leverage their CIR component(s)
    • Multiple CIR instances can be used
    • Registration CIR into AAI for ETSI Catalog Manager to find a proper instance of CIR
  • Access APIs to CIR will be Docker Registry APIs, by conforming to ETSI IFA040/SOL018
  • K8S CISM and CIS need to have their own way to find a proper CIR instance to pull Container Images.
• K8S CISM will obtain information on Container Image(s) thru Docker Registry APIs
• K8S CIS will pull Container Image(s) thru Docker Registry APIs
• The Interface between VNFM and K8S CISM will follow K8S APIs
  • Interface between VNFM and CISM: use k8s APIs, potential to leverage an alignment with O2-DMS
  • Interface between MultiCloud K8s Plugin and CISM: use k8s APIs, potential to leverage alignment with O2-DMS
  • VNFM Enhancement (PoC) to invoke CISM on O-Cloud through O2-DMS
  • Note: support O2-DMS is a stretch goal; most likely use K8S APIs

1.2 ONAP SO CNF Orchestration Support

...

• ETSI-Alignment path
  • Following ETSI NFV IFA specifications for CNF
  • Leveraging and extending existing ONAP ETSI-Alignment Architecture
• Direct Path
  • Some think there is no need for the full VNFD for LCM, just Helm Charts and Images; delegate LCM to CISM; it may work for simple CNFs
  • Note: there are several cases where a more complete VNFD will be needed, such as 5G Core NFs.
• Collaboration Areas:
  • Unified Modeling, Packaging & Onboarding (SDC) – optional VNFD?
  • Package Distribution (SDC – ETSI Catalog Manager – CIR)
  • Common Components (e.g., CIR, A&AI, CDS)
• Note: CIR will be realized by Nexus with Docker Registry (possibly migrate it to Github), and CIR access APIs will be based on Docker Registry APIs.

• SO / SO NFVO
  • SO NFVO continues to support the same SOL005 APIs API scope as Guilin: Create NS, Instantiate NS, Terminate NS, Delete NS and Get NS Operation Status.
    • In addition, It it will support NSD subscription and notification, interacting with ETSI Catalog Manager
    • However, SO NFVO will upgraded ETSI v3.3.1 SOL005 LCM APIs from ETSI v2.7.1 SOL005 LCM APIs

      • ETSI v3.3.1 SOL005 API swagger

        • Use the latest SOL005 API swagger from https://forge.etsi.org/jenkins/view/All+jobs/job/NFV+-+Network+Functions+Virtualisation/job/sol005-master/lastSuccessfulBuild/artifact/build/

    • Epics and User Stories: ONAP SO Hierarchical Orchestration (SO NFVO) - Honolulu#EpicandUserStory
  • SO NFVO Honolulu Architecture Highlights
    • SO NFVO will be invoked by Curl Commands (as SO NFVO Client) since the SOL005 Adapter enhancements are out of scope
    • SO NFVO NS Workflow BPMNs and business logic will be packaged as a war file and deployed to ONAP SO Standalone/Clustered Camunda Engine
      • Dynamic Orchestration support is a trial goal for Honolulu. In that case, NS Workflow BPMNs and business logic (with Embedded Camunda engine) will be part of SO NFVO, as is
    • SO NFVO and SOL003 Adapter communications will be treated as an internal communication via HTTP
    • SO NFVO interacts with ETSI Catalog Manager thru MSB for NSD subscription and notification

• Enhancements related to Container Image handling is a stretch goal

...

• • Most likely due to SDC 2MB file size limitation, Container Images will be uploaded to the CIR component by the Admin
  • i.e., in that case, no impact on ETSI Catalog Manager in Honolulu for Container Image handling

Image Added

• AAI
  • No impacts since the SO NFVO does not support Scaling or Healing
  • AAI impacts will be analyzed for the Istanbul release
