Hi Chenchuanyu, Please find my comments for your questions:
1. In R1 SDC would introduce a special type of VF to represent NS. The NS node type would include NS node properties as well as service_invariant_uuid and service_uuid. I should be able to share the full node description on Tuesday next week. 2. You can use the requirement and capabilities to define the dependencies between the VNFs and other resources (networks for example). This would define the sequencing. Important note: Although this is supported in SDC, based on my knowledge at the moment the sequencing is defined in a workflow which is created outside of SDC. Examples (using VoLTE E2E service): 1. The vIMS and vEPC are both depends on the underlayvpn network resource which means the orchestrator decompose into the following sequence: first, handle the underlayvpn and then vEPC and vIMS. Since there is no dependency between the vEPC and vIMS, it is up-to the orchestrator to decide the actual order (or do them both in parallel). [cid:image003.png@01D32248.7E0C2070] 2. Same as the previous model with the addition where vIMS is also depended on vEPC. Here the model specifically implies the vIME and vEPC instantiation order. [cid:image007.png@01D32248.7E0C2070] Again, I would like to emphasize that at the moment I don’t believe ONAP orchestrators (SO, VF-C) use the model (i.e., the relationships between the nodes) to identify the orchestration sequence. As far as I know, the sequence is captured in a workflow which is associated with the service/VNF.

The attached is the service CSAR downloaded. 2) We have discussed about VNF sequencing, I want to know how can I design a service with VNF sequencing in SDC portal , is there a guide for that?
