    The diagram under "ONAP model structure when consider Slicing service as a RFS" shows VF-C in common for all the NSS. VF-C would be applicable only for the Core NSS.

      Yes, you are right, this diagram is incompleted, will upadte it.

    HI,

    Looking at the first diagram in this page, I doubt about the meaning of the ServiceSliceDescriptor. The ServiceDescriptor is NOT an abstract class so you cannot instantiate it in a "ServiceSliceDescriptor". Trying to understand the purpose of the ServiceSlideDescriptor and define the right model, is ServiceDescriptor enough ? 


    The relation between ServiceDescriptor and ServiceSliceDescriptor is not defined in ONAP.

      Yes, ServiceDescriptor is enough, I just want to show the service profile and slice profile are used for network slice and network slice subnet respectively as discussed, it seems not a good expression, will make a change.

    Hi,

    Looking at the first diagram in this page, according to the ParameterGroup, DesignEntity and ServiceDescriptor defined in Enhanced Service Information Model for Nested and Shared Services, ServiceDescriptor has a relation with ParameterGroup. ParameterGroup is an abstract class and it can be instantiated with 3GPPServiceProfile. We do not need the SliceServiceProperties class. I do not understand the relation type between ParameterGroup and SliceServiceProperties.

      I think Kevin has answered your question, and I will make corresponding changes in this diagram.

    Chuyi Guo , Borislav Glozman : We should update the 3GPP figures (latest version of TS 28.530 shows 1:1 mapping between NSI and NSSI), as well as the modeling aspects based on the recent discussions, once we finalize the details.
