The NFV architecture enables network functions to be standardized, allowing for the construction and management of function or functions that best support the organization’s environment. This makes it easy for service providers and enterprises to deploy new services faster, while maximizing their investments in existing platforms.
As described in the introduction, there are three major components to an NFV framework:
- VNFs – Virtual Network Functions are the virtual implementation of a physical network function.
- NFVI – NFV Infrastructure represent the physical resources (compute, storage, network) and the virtual instantiations that make up the infrastructure.
- NFV MANO – NFV Management and Orchestration are the management and control layer that focuses on all the virtualization-specific management tasks required throughout the lifecycle of the VNF.
These components fit together in the architecture depicted in the diagram below. Note that this report focuses on the MANO element, the pieces on the right side of the diagram. The third part of our NFV series will focus on VNFs.
Here’s a graphical depiction of the NFV architecture, with the MANO components on the right side in blue.
