EthernetFrameClassifier¶

simple module EthernetFrameClassifier

Classifier that forwards Ethernet PAUSE frames to the pauseOut gate, and other frames to the defaultOut gate.

This component can be used to build a QoS queue that gives the PAUSE frames the highest priority.

Usage diagram¶

Inheritance diagram¶

Used in compound modules¶

Name	Type	Description
EthernetQosQueue	compound module	Queue module that gives the PAUSE frames a higher priority, and can be parametrized with an IPacketQueue for serving the data frames.
EthernetQosRedQueue	compound module	Queue module that gives the PAUSE frames a higher priority, and using Random Early Detection algorithm on data frames, and can be parametrized with an IPacketQueue for serving the data frames.

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	“classified %p pk (%l)”	Determines the text that is written on top of the submodule, supports displaying pars, watches, and module-specific information
reverseOrder	bool	false

Properties¶

Name	Value	Description
class	EthernetFrameClassifier
display	i=block/classifier

Gates¶

Name	Direction	Size	Description
in	input
out [ ]	output

Signals¶

Name	Type	Unit	Description
packetPushed	inet::Packet

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
