24、TSI GR NFV-IFA 015 i.1, is focused on the management of the virtualisation aspects. Other models exist defined by other organizations and to provide an end-to-end model view, it is useful to be able to federate the NFV Information Model with other external models. The approach used is to define inte

25、raction points between the NFV Information Model and some models from other organizations, allowing all organizations to extend their model based on the interaction points as they see needed. The NFV Touchpoint Model, provided in annex A, only describes the touchpoints between various models. The cl

26、asses involved from each external model are defined in separate Papyrus models. Both those external Papyrus models as well as the NFV Information Model are loaded as read-only in the NFV Touchpoint Model to create the needed relations between the models. This allows the NFV Information Model to rema

27、in independent of any external model. 4.2 Relation to other ETSI NFV ISG Specifications The present document is referencing information from the following ISG NFV Group Specifications: Network Function Virtualization (NFV); Management and Orchestration; Report on NFV Information Model ETSI GR NFV-IF
