26、 UMLi.3 NFV Information Model. The intention of the information model is to provide a consolidated view on all information elements present as part of the interface specifications. The model is a tool to check consistency between information elements as well as to provide a logical relationship betw

27、een information elements across different interfaces by the use of UMLassociations. The model is structured into domains and modules to differentiate between different types of information elements and their use. Whereas the Core Model provides generic information elements which are applicable to mu

28、ltiple interfaces, the Interface Information Model provides interface specific information elements. NOTE: The term Core Model is used within the scope of the present document and is not related to the term Core Model used outside of the ISG. In case of discrepancies between the present document and

29、 information elements specified in the documents in clause 4.2, the latter are considered as the reference. The format of the model will be UMLi.3, using the Papyrus Open Source format i.2. 4.2 Relation to other ETSI NFV ISG Group Specifications The present document is referencing information from t

30、he following NFV Group Specifications: NS Templates information elements, produced by ETSI GS NFV-IFA 014 i.11; VNF Descriptor information elements produced by ETSI GS NFV-IFA 011 i.9; Information elements produced by ETSI GS NFV-IFA 005 i.5, ETSI GS NFV-IFA 006 i.6, ETSI GS NFV-IFA 007 i.7, ETSI GS

Release 2 ETSI ETSI GR NFV-IFA 015 V2.1.2 (2017-01) 7 5 About the NFV Information Model 5.1 Model structure The NFV Information Model, as shown in figure 1, is organized in an NFV Core Model and extensions, extending the NFV Core Model for specific need

32、s. One extension, NFV Interface Information Model, is currently defined for containing information elements specific to interfaces. Figure 1: NFV Information Model structure Each model is structured in Domains. Four domains are defined today: NFV Common Domain Virtualised Resource Domain VNF Domain

33、NS Domain Each domain is structured in modules. 5.2 Model views 5.2.1 Introduction The NFV Information Model includes 3 types of view: Logical view Deployment view Application view Release 2 ETSI ETSI GR NFV-IFA 015 V2.1.2 (2017-01) 8 5.2.2 Logical view The logical view is concerned with the functio

34、nality that the system provides to end-users. Most of the classes in the model belong to the logical view. To facilitate recognition, all elements that are part of the logical view are coloured in light blue in the diagrams. Figure 2 is showing a very basic example of a VNF logical view. Figure 2: B

35、asic example of a VNF logical view 5.2.3 Deployment view The deployment view is concerned with the functionality that is needed to deploy the provided system to end-users. All the descriptor classes are part of the deployment view. To facilitate recognition, all elements that are part of the deploym

36、ent view are coloured in yellow in the diagrams. Figure 3 is showing a very basic example of a VNF deployment view. Release 2 ETSI ETSI GR NFV-IFA 015 V2.1.2 (2017-01) 9 Figure 3: Basic example of a VNF deployment view As the elements in the deployment view are used to deploy elements in the logical

37、 view, corresponding elements are related as shown in the example of a relationship between logical and deployment views in the figure 4. Figure 4: Example of a relationship between logical and deployment views 5.2.4 Application view The application view is concerned with the functionality that the

38、application provides to end-users. To ease integration with other information models, relationship between key elements in the logical view and some application elements are present in the NFV Information Model. These application elements, in limited number, are out of ETSI NFV scope and are just pr

39、esent as empty classes. To facilitate recognition, all elements that are part of the application view are coloured in purple in the diagrams. Release 2 ETSI ETSI GR NFV-IFA 015 V2.1.2 (2017-01) 10 The figure 5 is showing an example of a relationship between logical and applications views. Figure 5:

40、Example of a relationship between logical and application views 5.3 Model details The model details are provided in Papyrus i.2 format in the attached zip file which accompanies the present document. The Gendoc plugin i.4 is used to generate a Microsoft Word output of the NFV Information Model. The

41、model is decomposed based on the model structure presented in clause 5.1 and, for each module, the following elements are listed in order: Diagrams Classes Notifications Datatypes Associations For each element, the comments and the stereotypes are shown. For classes, notifications, and datatypes, th

42、e attributes are displayed in tables. For associations, the association ends, whether the association is navigable or not, are shown in tables.
