• SOL001/SOL004 Standard Conformance

  • VNF Package

    • A VNF Package is a compressed file that contains the following:
      • One VNF descriptor (VNFD)
      • One or more Software Image files
      • Zero or more manifest files
      • Other files

    • Package structure is SOL004 2.5.1 compliant.

    • Note: SDC in Dublin has limitations and restrictions on SOL004 support:
      • SDC does not allow custom directories such as Images, Scripts, Licenses and HOT in the root directory.
      • SDC requires MainServiceTemplate.mf and MainServiceTemplate.yaml in the root directory
      • As a result, in Dublin, the vendor VNF package should follow SDC onboarding rules. These SDC restrictions and limitations plan to be removed in the El Alto release. 

  • Cloud Service Archive (CSAR) format

    • It is a packaging construct defined in SOL004 2.5.1, identified by a .csar suffix on the package file. In SOL004, there are two package options; one with TOSCA-Metadata, one without TOSCA-Metadata directories: 

      • The CSAR file does not contain TOSCA-Metadata directory, the descriptor yaml file is in the root directory of the CSAR.

      • The CSAR file contains TOSCA-Metadata directory, the TOSCA meta file in this directory contains the location and name of the descriptor file denoted by Entry-Definitions

    • In ONAP, the second option (with TOSCA-Metadata) is supported.
    • Note: in SDC El Alto, if the VNF package with certificate and/or signature will be packaged as a zip file. The csar format continues to be used for the package without certificate and/or signature. The zip file without certificate and/or signature will be considered as an HEAT-based package.

  • VNFD

    • It is specified by the SOL001 2.5.1.

    • Note 1: that the input and get_input function would be used by a TOSCA orchestrator at run time to access the selected input parameter. If the deployment is not done by a TOSCA orchestrator, the inputs and get_input function may not be needed. The VNFD design should follow the vendor SVNFM orchestration capabilities. 
    • Note 2: in Dublin, SDC will convert SOL001 VNFD to SDC AID DM, but it is not complete. More mapping design discussions are necessary in El Alto.
