Adding Connections

A connection is a physical link between two processors, two devices, or a processor and a device. Most commonly, connections represent the physical network connections between the nodes on your network. A connection can also be an Internet link between two nodes.

To add a connection:

1.

Select Connection from the toolbox.

2.

Click on the node to connect.

3.

Drag the connection line to another node.

OR

1.

Select Tools → Create → Connection.

2.

Click on the node to connect.

Press Delete.

OR

1.

Select the connection in the diagram.

2.

Select Edit → Delete.

Adding Connection Details

Connections may be assigned stereotypes. Connections can also be given characteristics, which are used to provide details about the physical connection. For example, a connection might be a T1 line. This type of note would be added in the Characteristics field.

To assign a stereotype:

1.

Open the desired connection's specification window.

2.

Select the General tab, as shown in Figure 11.6.

Adding Processes

A process is a single thread of execution that runs on a processor. An executable file, for example, is considered a process. When adding processes to the diagram, focus on only the processes related to the system being built.

Processes can be displayed on a Deployment diagram or hidden from view. If they are displayed, they are listed directly below the processor(s) on which they are run.

Processes may be assigned a priority. If the processor on which they are run uses preemptive scheduling, the priority of the process will determine when it can run.

To add a process:

1.

Right−click the desired processor in the browser.

2.

Select New → Process from the pop−up menu.

3.

Enter the name of the new process.

OR
