Inheritance diagram

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

Known subclasses

Name	Type	Description
InstantServer	simple module	This module repeatedly pulls packets from the connected packet provider and pushes the packet into the connected packet consumer without delay.
PacketServer	simple module	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.
PreemptingServer	simple module	(no description)
TokenBasedServer	simple module	This module repeatedly pulls packets from the connected packet provider and it pushes them into the connected packet consumer. The packets are processed in zero simulation time, and the process continues until the available number of tokens is not sufficient anymore.

Extends

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

Parameters

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