MultiFieldClassifier¶

simple module MultiFieldClassifier

This classifier contains a list of filters that identifies the flows and determines their classes. Each filter can match the source and destination address, IP protocol number, source and destination ports, or ToS of the datagram. The first matching filter determines the index of the out gate. If no matching filter is found, then the packet will be sent through the defaultOut gate.

See RFC 2475 2.3.1, RFC 3290 4.2.2

Extends¶

Name	Type	Description
PacketClassifierBase	simple module	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	“{mfClassifierStatus}”	Determines the text that is written on top of the submodule, supports displaying pars, watches, and module-specific information
reverseOrder	bool	false
filters	xml	xml(“<filters/>”)

Properties¶

Name	Value	Description
class	MultiFieldClassifier
display	i=block/classifier

Gates¶

Name	Direction	Size	Description
in	input
out [ ]	output
defaultOut	output

Signals¶

Name	Type	Unit	Description
packetPushed	inet::Packet
pkClass	long

Statistics¶

Name	Title	Source	Record	Unit	Interpolation Mode	Description
dataRate	data rate	throughput(packetPushed)	vector	bps	linear	the statistical value is the data rate of the classified packets
packetLengths	packet lengths	packetLength(packetPushed)	sum,histogram,vector	b	none	the statistical value is the length of the classified packet
packets	packets	packetPushed	count	pk		the statistical value is the classified packet
pkClass	packet class	pkClass	vector		none
