Traditional network architectures based upon purpose-built network appliances and the resulting complex manual and proprietary systems interfaces used to support a rapidly increasing diversity of network appliances have been identified as the root causes of high-cost, poor capacity scaling, and long deployment and innovation cycles. This is affecting the sustainability of network operators’ business models. As a result, network operators have launched their NFV initiatives to overcome the limitations of traditional network architecture. NFV is explicitly designed to reduce cost, and increase network scalability and agility. 

ACG's whitepaper shows that the common platform approach is uniquely able to support a sustainable business model through implementation of NFV and that appliance-based and NFV custom vertical software stack approaches are likely to fail.
