This module repeatedly pulls packets from the connected packet provider and after a processing delay it pushes the packet into the connected packet consumer. The processing delay is processingTime + packetLength / processingBitrate.

Inheritance diagram

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

Extends

Name	Type	Description
PacketServerBase	simple module	This is a base module for various packet server modules.

Parameters

Name	Type	Default value	Description
displayStringTextFormat	string	"served %p pk (%l)\n%s"	determines the text that is written on top of the submodule

serveSchedulingPriority	int	-1	specifies the FES scheduling priority for the extra event that is pulling the packet, -1 means no extra event
processingTime	double		determines additional processing time per packet
processingBitrate	double	inf bps	determines additional processing time per bit
