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. + +.. req:: + :id: R-15837 + :target: VNF + :keyword: MUST + :introduced: casablanca + + The following table defines the major TOSCA Types specified in + ETSI NFV-SOL001 standard draft.
