scope:

The present document investigates the aspects of NFV that have an impact on power consumption and energy efficiency, including but not limited to:

• the design and runtime characteristics of the NFV framework, including VNF, NFVI, NFV-MANO, etc. which can influence energy consumption;

• the deployment configuration of NFV-MANO systems and their optimization in various scenarios such as small footprint but highly distributed deployments; and

• the mechanisms that enable the collection of energy related information, smart energy usage and decision making in NFV considering NFV capabilities such as orchestration and automation.

The present document also documents potential solutions, and where applicable, it also provides recommendations for enhancements to the NFV architectural framework and its functionality aiming to provide further support to address energy efficiency objectives.
