This page is used for the ONAP R2+ Resource IM drafting and discussion.

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?
    - No model for network port?
  
  Is the VNF Instance model still under discussion like the VNFD model?
  
  2) ETSI IFA IM (IFA015 VNFLogicalModel diagram)
  

• Design Time Model

  1) ONAP Resource Model UML
  
  

• 
  
  2) ETSI IFA IM (IFA015 VNFD)
  
  (besides VduCpd, Vdu also has relationship with VirtualComputeDesc, VirtualStorageDesc and swImageDesc; which are omitted in this diagram)
  
  3) SDC IM (normative and heat types)
  

(omit several types for simplicity)
