The ETSI Industry Specification Group for Network Functions Virtualization (ISG NFV) has just published its specifications of version 4.5.1 (except for NFV006, which is to be published separately). In this version, container-related functionalities have been completed (such as the support for container cluster management), and new features have been added, both in stage 2 and stage 3 (such as flexible VNF deployment, certificate management and fault management model). Version 4.5.1 is the final for NFV Release 4 and version 4.6.1 is only maintenance.

The enhancements of the architecture enable the NFV framework to support Certificate Management Function (CMF) and Intent Management (IM). Certificate Management strengthens the security of both communication between VNFs and communication between NFV-MANOs internally, and enables certificate verification in multi-vendor environment. Intent Management helps NFV-MANO to support intent based management interfaces between the NFVO and its consumers.

In addition, stage 2 version 4.5.1 specifications include support to Fault Management model to unify alarms type, interface between CIS Cluster Management (CCM) and Virtualised Infrastructure Manager (VIM), and the new Flexible VNF deployment feature.

The stage 3 specifications related to the support for containerized workloads have been enhanced e.g.: to strengthen security and to provide guidance via MANO procedures. The new stage 3 CIS Cluster Management (CCM) specification, enhancement of existing interfaces to support Certificate Management, and new Flexible VNF deployment feature are part of this version.
