Work on our third release of NFV specifications has begun
in earnest. The main objectives of Release 3 are to provide
consistent operational integration with connectivity services,
to consolidate security mechanisms and to enable the
support of multi-domain scenarios suitable for potential new
business models. During the development of Release 3,
we will identify and address the additional requirements
for NFV technologies as a result of the evolution of
telecommunications networks, particularly 5G, and we will
explore questions related to multi-domain and multi-tenancy,
considering issues such as licensing, accounting and charging.

Our work also includes the development of a consolidated
set of protocols and data model specifications to support
interoperability. By mid-2017 the first Stage 3 specifications
