Vdu

The Virtualisation Deployment Unit (VDU) is a construct supporting the description of the deployment and operational behavior of a VNFC.   A VNFC instance created based on the VDU maps to a single virtualisation container (e.g. a VM).  A VNFC will only be in one VNFDesc.   If a vendor wants to use the VNFC in mupliple VNFDesc (their product) they can do so, but it will be 'repeated'.
