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)
