Compared to the PNF approach, NFV allows Functions to be packaged as a Virtual Machine (VM) or as a “Container”, e.g. LXC / Docker. Each vendor will have a questionaire that will be used as an input to estimate the number of Virtual Resources (Memory, CPU, Networking, Storage, etc..) that will be required. MANO will be used to help to setup and deploy the required VMs on a Data Center(s).
