One of the greatest advantages of network functions virtualization and cloud network architectures is the ability for network operators to dynamically scale the capacity of their networks to better mirror demand without having a significant amount of capacity laying dormant, waiting for busy-hour spikes in traffic.
With NFV/cloud deployments, capacity changes based on need. All of the efficiency offered by elastic demand would disappear if the capacity was licensed in a traditional manner. Therefore, there needs to be licensing and revenue models that reflect this new reality.
