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

Name	Required	Type	Description

Name	Required	Type	Description
host	yes	^{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.

Examples

Extending the basic NetworkFunctionComponent with 2 port bindings and 1 storage attachment. Each of its extra Bindable-typed capabilities has its own descriptive name and sub-type.
