- 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;
- VNF lifecycle management (LCM) operations: describes the LCM operations supported per deployment flavour, and their input parameters; Note, that the actual LCM implementation resides in a different layer, namely referring to additional template artifacts.
R-XXXXXXXX: The following table defines the major TOSCA Types mapped from ETSI NFV VNFD model to TOSCA Simple Profile for NFV version 1.0 specificationTOSCA Node Types specified in ETSI NFV-SOL001 standard draft. The VNFD provided by a VNF vendor MUST comply with the below definitions:
