Traffic Generators

When a path has been identified by the application, it attaches a traffic generator to the source endpoint (simple equipment model) of the path. (A path would be of little value to the simulation if you could not cause traffic to traverse it.) A traffic generator gives you control over the rate at which simulated calls are generated from this source and also how long the calls last. If you can call multiple destinations from this source (that is, there are multiple paths from this source), you can also set the probability that the call will be placed to each possible destination through the traffic generator.

When an equipment model has a traffic generator attached to it, the Edit Attributes dialog box will have a push button for displaying the generator's control panel. A sample traffic generator control panel is shown in Figure 3.9.

The controls labelled Hold Distn determine how long a simulated call will last (that is, the time between the path being seized and subsequently released), and the controls labelled Rate Distn determine the time between calls. Clicking the

button creates a new window in which you can edit the probabilities associated with a call being placed to each destination.
