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 background enter the scene

fight the vendor lock-insimpler network elements

Automation and Openness ...

• 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
