Comparison of Current R3 Clean Version with IFA011 v2.5.1

This page shows the differences between the current clean version model with ETSI IFA011 v2.5.1 and other proposed changes:

Verified against IFA011 v2.5.1 and IFA015 v2.5.1
Added "Attribute Type" column to indicate whether the class attribute is an "attribute" or member end of an "association". Without this information it is difficult to create a class diagram. We might want to consider also for those "Attribute Types" that are associations to put whether there is shared or composite aggregation, or no aggregation at all. Note: This will not be necessary when model is put into Papyrus, as all associations will start with "_"
Changed attribute Applied Stereotypes to represent the actual stereotypes being applied, and not just a property of a stereotype. Note: When the model is in Papyrus, GenDoc will output this field correctly.
Added class definitions and applied stereotypes. Note: GenDoc will do this correctly when the model is in Papyrus.
Proposal to define actual enums and not use the general term "Enum". Make sure the model captures these correctly in Papyrus.
Proposal to remove incorrect usage of valueRange in OpenModelAttribute stereotype. Make sure this is not incorrectly propagated to Papyrus.

Class: Vnfd

A VNFD is a deployment template which describes a VNF in terms of deployment and operational behaviour requirements. It also contains connectivity, interface and virtualised resource requirements.
