Description

A templates of this type are atoms of application logic, and they must be hosted. 

They are expected to have connection point bindings and are used to compose a Network Function, particularly a virtual one.

Nodes of this type are normally concrete, implemented using deployment artifacts.

Attributes

Nothing special

Capabilities

Types derived from onap.nodes.NetworkFunctionComponent normally extend it by at least one capability of type onap.capabilities.Bindable.


Requirements


NameRequiredTypeDescription
hostyes
tosca.capabilities.Container
A Network Function Component must be hosted. This requirement is normally paired with the host capability of a Compute-typed node. It can also be paired with the host capability of a Container-typed node.
