Overview
OSM supports descriptors for Virtual Network Functions and Network Services. The data models for these descriptors are aligned with ETSI MANO [1].
Virtual Network Function Descriptor [VNFD] defines the VNF and resources required for realizing the network function. The descriptors includes various components that are part of the VNF. In addition, VNFD also defines the VNF level configuration information.
Network Service Descriptor [NSD] defines a set of interconnected VNFs to realize a network service spanning multiple VNFs. In addition, NSD also defines the NS level configuration information.
Network Service Descriptor
The NSD connects VNFs using the Virtual Links (VLs) as shown in the following diagram:
The VNFs attach to the VLs using the Connection Points (CPs). So the NSD captures the list VNFs and the VLs that connect the VNFs. The following diagram illustrates the high level objects in an NSD:
An example NS containing an IMS VNF is here.
