2.15 Virtualized network functions manager VNF

Network Function Virtualization-Management and Network Orchestration (NFV-MANO) architecture is the framework created for performing the necessary management and orchestration by ETSI standards. DSR 9.0.0.0.0includes a VNFM for automating life cycle management operation of DSR application.

DSR VNFM is a standalone VM deployed separately from the DSR VNFCs. The DSR VNFM provides a REST API where in subset of VNF specific function provided in ETSI NFV SOL 003 can be supported. DSR VNFM provides supports ETSI direct model to interface with Open Stack and providing HEAT templates to deploy DSR/vSTP applications.

DSR application automatic instantiation process includes two operations specified by the ETSI NFV SOL 003.Those operations supported by DSR VNFM currently are as follows:

Create VNF Identifier
Instantiate VNF
VNFC Scale Out capabilities
Query Life Cycle Management
Auto Discover capabilities
Terminate VNF
