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

Extends

Name	Type	Description
PacketMarkerBase	simple module	This is a base module for various packet marker modules. Derived modules must implement a single markPacket() function which marks the individual packets by attaching tags.

Parameters

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

Properties

Name	Value	Description
display	i=block/rightarrow
class	EcnMarker

Gates

Name	Direction	Size	Description
in	input
out	output

Signals

Name	Type	Unit
packetPushedIn	inet::Packet
packetPulledIn	inet::Packet
packetPushedOut	inet::Packet
packetPulledOut	inet::Packet

Statistics

Name	Title	Source	Record	Unit	Interpolation Mode
