Creating NSV-2 Systems Communication diagrams for NAF
You create the systems communication diagram to provide more detail to the system interfaces that are seen on the NSV-1 systems interface diagram.
This diagram adds to the single-line representation of the interfaces shown on the SV-1 diagram detail about the communication infrastructure. Depending on the focus of the architecture, the diagram can present you with an internodal or intranodal perspective. The internodal approach details the communication paths and networks that internally connect system nodes or specific systems. The intranodal approach looks in the system nodes to pinpoint the interfaces between specific containing nodes.
1 Click File > New Diagram.
2 In the Select New Type for All Methods dialog box, double-click NSV-02 Systems Communication.
3 In the New Diagram dialog box, type a name for the diagram; then click OK.
4 To draw the diagram, click Draw, select elements from the list, and then click an area in the diagram.
You can add the following symbols to the systems communication diagram:
System Node Interface: Allows data to be passed only between system node symbols.
System Node: Describes the operation or role and allocation of resources to perform a particular role or operation.
System Interface: Allows data information to be exchanged only between System Entities.
System Entity: Describes the system functions that need to be preformed
Communications Node: Controls the transfer and movement of information.
Communications Connection: The connection can describe the nature of the communication path, such as the kind of channel or network.
5 To save the diagram, click File > Save Diagram.
