BehaviorAggregateClassifier¶

simple module BehaviorAggregateClassifier

Reads the DSCP (lower six bits of ToS/TrafficClass) from the received datagram, and forwards the datagram to the corresponding output gate.

DSCPs are enumerated in the dscps parameter, first value is for out[0], second for out[1], etc. If the packet has no DSCP, or its value is not enumerated in the dscps parameter, it will be forwarded via the defaultOut gate.

Usage diagram¶

Inheritance diagram¶

Used in compound modules¶

Name	Type	Description
DiffservQueue	compound module	This is an example queue that can be used in interfaces of DS core and edge nodes to support the AFxy (RFC 2597) and EF (RFC 3246) PHBs.

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	“{classifierStatus}”	Determines the text that is written on top of the submodule, supports displaying pars, watches, and module-specific information
reverseOrder	bool	false
dscps	string	“”	Space-separated dscp values of the gates, both names (e.g. AF11, EF) and numbers (0x0A,0b101110) can be used

Properties¶

Name	Value	Description
class	BehaviorAggregateClassifier
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
