This module classifies packets based on the stream they are part of. The stream is determined by a StreamReq or a StreamInd or both.

Inheritance diagram

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

Extends

Name	Type	Description
PacketClassifierBase	simple module	This is a base module for various packet classifier modules. Derived modules must implement a single packet classifier function which determines the index of the output gate for the next pushed packet.

Parameters

Name	Type	Default value	Description
displayStringTextFormat	string	"classified %p pk (%l)"	determines the text that is written on top of the submodule
reverseOrder	bool	false
mode	string	"both"
mapping	object	{}	maps stream name to gate index
gateIndexOffset	int	0	specify value to be added to the mapping output gate index
defaultGateIndex	int	0	default gate index if no matching streams are found

Properties

Name	Value	Description
display	i=block/classifier
class	StreamClassifier

Gates

Name	Direction	Size	Description
in	input
out [ ]	output

Signals

Name	Type	Unit
packetPushed	inet::Packet

Statistics

Name	Title	Source	Record	Unit	Interpolation Mode
packetLengths	packet lengths	packetLength(packetPushed)	sum, histogram, vector	b	none
dataRate	data rate	throughput(packetPushed)	vector	bps	linear
packets	packets	packetPushed	count	pk
