Use cases and scenarios
=======================
resources (VMs in this example) shown with the same colors.
The first requirement in this use case is that the Controller needs to detect
-faults in the NVFI ("1. Fault Notification" in :numref:`figure1`) affecting
+faults in the NFVI ("1. Fault Notification" in :numref:`figure1`) affecting
the proper functioning of the virtual resources (labelled as VM-x) running on
top of it. It should be possible to configure which relevant fault items should
be detected. The VIM (e.g. OpenStack) itself could be extended to detect such
except in this case, the Consumer of a VM/VNF switches to STBY configuration
based on a predicted fault, rather than an occurred fault.
