NFV Creates Opportunities ...
NFV promises: faster service delivery, rapid service innovation, simpler architecture,
openness avoid vendor lock-in
Operators act on this; see e.g. Telefonica/HP announcement on March 3rd:
announced March 3, 2015
30% of network shall be
NFV enabled in 2016
New players with IT

• OPEX savings require high-level of automation
• Fast service introduction with standardized
software layering (“open NFV hosting”)
• System integration savings require
standardized control interfaces
• Open management and orchestration
• Open programming of flows
