C++ definition

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
PacketDelayerBase	simple module	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.

schedulingPriority	int	0
scheduleZeroDelay	bool	true
delay	double		Specifies delay per packet
bitrate	double	inf bps	Determines additional delay per bit
