Protocol layer (UPDM - DoDAF aliases)
Creation
To create a Protocol Layer:
• From a Protocol: right-click the Protocol, point to New, point to DoDAF, and then click Protocol Layer.
On the Select Type dialog, create or select the Protocol element that is the type of the Protocol Layer, or create an untyped Protocol.
• From an StdV-2 Standards Definition:
◦ Click the Protocol Layer toolbar button, and then click the owning Protocol. On the Select Type dialog, create or select the Protocol element that is the type of the Protocol Layer, or create an untyped Protocol.
◦ Click the Composite Association toolbar button, click the owning Protocol, and then click the Protocol element that is the type of the Protocol Layer.
You can also create Protocol Layer elements through the Association and Uni-Directional Association toolbar buttons.
• From an StdV-2 Protocol Layer Definition:
◦ Click the Protocol Layer toolbar button, and then click the owning Protocol or Protocol Layer. On the Select Type dialog, create or select the Protocol element that is the type of the Protocol Layer, or create an untyped Protocol.
If the Protocol that owns the StdV-2 Protocol Layer Definition is not shown on the diagram, create a Protocol Layer on that Protocol by clicking in free space.
◦ From an appropriate Modeler pane, locate the Protocol element that you want to use as the type of the Protocol Layer, and then drag that Protocol to the Protocol or Protocol Layer on the diagram.
If the Protocol that owns the StdV-2 Protocol Layer Definition is not shown on the diagram, create a Protocol Layer on that Protocol by dragging the type to free space on the diagram.
Appearance
When shown on an StdV-2 Standards Definition, a Protocol Layer appears as follows:

Relationships
There are no relationships that are of significant importance to a Protocol Layer.
The following sections provide information about how a Protocol Layer is used in the model.
