PacketDelayerBase¶

simple module PacketDelayerBase

Base module for packet delayer implementations. Provides common functionality for delaying packets for a specified amount of time before forwarding them. Supports clock synchronization, scheduling priorities, and zero-delay handling. Adds delay-related tags to packets for tracking and analysis.

Inheritance diagram¶

Known subclasses¶

Name	Type	Description
EthernetCutthroughBarrier	simple module	(no description)
PacketDelayer	simple module	Connects one packet producer to one packet consumer. It can be pushed with packets from the connected packet producer. When this happens, the packet is delayed and eventually pushed to the output. Note that the order of packets may change if the delay parameter is configured to be a distribution.

Extends¶

Name	Type	Description
PacketProcessorBase	simple module	Base module for various packet processing modules which maintains a few statistics.

Parameters¶

Name	Type	Default value	Description
displayStringTextFormat	string	“processed {numProcessedPackets} pk ({processedTotalLength})”	Determines the text that is written on top of the submodule, supports displaying pars, watches, and module-specific information
clockModule	string	“”	Relative path of a module that implements IClock(1,:ref:2 <neddoc-msg-inet-iclock>); optional
schedulingPriority	int	0
scheduleZeroDelay	bool	true

Properties¶

Name	Value	Description
class	PacketDelayerBase
display	i=block/delay

Gates¶

Name	Direction	Size	Description
in	input
out	output
