This module is an active packet source which pushes packets into the connected packet consumer.

Inheritance diagram

The following diagram shows inheritance relationships for this type. Unresolved types are missing from the diagram.

Used in compound modules

Name	Type	Description
BurstyPacketProducer	compound module	This module mixes two different packet sources to generate bursty traffic.

Extends

Name	Type	Description
ActivePacketSourceBase	simple module	This is a base module for various active packet source modules.

Parameters

Name	Type	Default value	Description
displayStringTextFormat	string	"created %p pk (%l)"	determines the text that is written on top of the submodule
packetNameFormat	string	"%a-%c"	see directives in module documentation
packetRepresentation	string	"byteCount"	determines the chunk of the packet data
packetLength	int
packetData	int	-1
attachCreationTimeTag	bool	true
attachIdentityTag	bool	true
attachDirectionTag	bool	true
clockModule	string	""	relative path of a module that implements IClock; optional
initialProductionOffset	double	0s
productionInterval	double		elapsed time between subsequent packets pushed to the connected packet consumer
scheduleForAbsoluteTime	bool	true	when a clock is used relative means that setting the clock will not affect the simulation time of the event
