This module is a passive packet source which can be pulled for packets from the connected packet collector.

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
ResponseProducer	compound module	This module is capable of generating several different streams of packets, one after the other. For each traffic category, the packets are produced by a separate token based server. The traffic stream can be started by adding tokens the corresponding server module. The packet data, packet length, and timing distributions can be configured in the corresponding packet provider.

Extends

Name	Type	Description
PassivePacketSourceBase	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
packetProtocol	string	"unknown"
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
initialProvidingOffset	double	0s	initial duration before which packets are not provided
providingInterval	double	0s	elapsed time between subsequent packets allowed to be pulled by the connected packet collector, 0 means any number of packets can be pulled at the same simulation time
scheduleForAbsoluteTime	bool	true	when a clock is used relative means that setting the clock will not affect the simulation time of the event
