The VNF package provided by a   VNF vendor **MAY** be either with TOSCA-Metadata directory (CSAR Option 1) or   without TOSCA-Metadata directory (CSAR Option 2) as specified in ETSI GS   NFV-SOL004. On-boarding entity (ONAP SDC) must support both options. 

**Note:** SDC supports only the CSAR Option   1 in Casablanca. The Option 2 will be considered in future ONAP releases,VNFMAYVNF Package Structure and Format

The VNF provider MUST enumerate all of the open source licenses their VNF(s) incorporate. CSAR License directory as per ETSI SOL004.

for example ROOT\Licenses\ License_term.txt

The VNF Descriptor (VNFD) provided by VNF vendor MUST comply with TOSCA/YAML based Service template for VNF descriptor specified in ETSI NFV-SOL001.

Note: As the ETSI NFV-SOL001 is work in progress the below tables summarizes the TOSCA definitions agreed to be part of current version of NFV profile and that VNFD MUST comply with in ONAP Release 2+ Requirements.

A VNFD is a deployment template which describes a VNF in terms of deployment and operational behavior requirements. It contains virtualized resources (nodes) requirements as well as connectivity and interfaces requirements and MUST comply with info elements specified in ETSI GS NFV-IFA 011. The main parts of the VNFD are the following:

• VNF topology: it is modeled in a cloud agnostic way using virtualized containers and their connectivity. Virtual Deployment Units (VDU) describe the capabilities of the virtualized containers, such as virtual CPU, RAM, disks; their connectivity is modeled with VDU Connection Point Descriptors (VduCpd), Virtual Link Descriptors (VnfVld) and VNF External Connection Point Descriptors (VnfExternalCpd);
• VNF deployment aspects: they are described in one or more deployment flavours, including configurable parameters, instantiation levels, placement constraints (affinity / antiaffinity), minimum and maximum VDU instance numbers. Horizontal scaling is modeled with scaling aspects and the respective scaling levels in the deployment flavours;

Note: The deployment aspects (deployment flavour etc.) are postponed for future ONAP releases.

• VNF lifecycle management (LCM) operations: describes the LCM operations supported per deployment flavour, and their input parameters; Note, thatthe actual LCM implementation resides in a different layer, namely referring to additional template artifacts.

The VNF provider MUST provide the binaries and images needed to instantiate the VNF (VNF and VNFC images) either as:

• Local artifact in CSAR: ROOT\Artifacts\ VNF_Image.bin
• externally referred (by URI) artifact in Manifest file (also may be referred by VNF Descriptor)

Note: Currently, ONAP doesn’t have the capability of Image management, we upload the image into VIM/VNFM manually.
