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?
