scope:

The present document contains a feasibility study on the application of a Service-Based Architecture (SBA) design style to the NFV-MANO architectural framework specified in ETSI GS NFV 006 [i.1]. This includes - but is not limited to - studying aspects such as making interfaces independent from reference points, identifying new functionality related to NFV services like service registration.

The present document provides recommendations on the evolution of the ETSI ISG NFV specifications structure and on normative work to be carried out to apply SBA design patterns to the NFV architectural framework, as well as solutions and recommendations for coexistence of SBA NFV-MANO with the non-SBA NFV-MANO architecture and for migration to an SBA target.
