UML Comparison

This section illustrates the core IM design related to VNF resource from different sources.  

  • Run Time Model (VNF Instance)

    1) ECOMP IM (vNF deployment diagram)

    Questions:
      - What's the relationship between VNFC instance and VNF module? What's the usage of VNF module?
      - Why does network only associate with the VM, but not with Docker/LXC? Why is the cardinality 1:1?
      - Why does storage have no association with VNFC instance?
      - Why does VNFImage have 1:1 association with VNF instance, instead of VNFC instance?

    2) ETSI IFA IM (IFA015 VNFLogicalModel diagram)

  • Design Time Model

    1) ECOMP IM (VNFCatalogItem)


    2) ETSI IFA IM (IFA015 VNFD)

    3) SDC IM (normative and heat types)
