  This paper aims to propose one possible approach in the setting of VHCNs
(Very High Capacity Networks) performance targets that should be capable of
promoting efficient investments for operators and, at the same time, improving
the benefits for end-users. To this aim, we suggest relying on some specific
KPIs (Key Performance Indicators), especially throughput - i.e., the bandwidth
as perceived by the customer - valid at the application layer, instead of the
physical layer data-rate. In this regard, the paper underlines that the
bandwidth perceived is strictly linked to the latency. The most important
implication is that some of the most demanding services envisaged for the
future (e.g., mobile virtual and augmented reality, tactile internet) cannot be
met by merely increasing the low-level protocol data-rate. Therefore, for the
VHCNs reducing latency through Edge Cloud Computing (ECC) is a mandatory
pre-requisite.
