Description

Many common use cases involve VNFs that are composed of several types of VDUs that need to be scaled and operated independently but still belong to the same VNF and, hence, need to be completely described in the VNF Package, not at NS level.

Some common examples are composite VNFs -such as IMS or EPC- or simple but decomposed VNFs, such as a vRouter with control and data plane that are intended to run in separate VMs.

Demo or definition of done

• A VNF Package of a VNF composed of more than one type of VDUs (e.g. 2 types of VNUs: user and data plane) is successfully onboarded in the system. The set of primitives available is unified at VNF level.
• The VNF is properly deployed, with the VMs interconnected as specified in the descriptor and the VNF as a whole can be operated with VNF primitives.
