8 likes•6,379 views
The document discusses the work of the ETSI NFV Interfaces and Architecture Working Group (IFA WG). It provides an overview of the MANO architectural framework, including basic concepts, the architectural framework diagram, and information model. It also maps the MANO components to IFA work items, such as specifications for reference points and interfaces. Finally, it shows how the VIM northbound interfaces are mapped to relevant OPNFV projects.
