EtherTrafGen

simple module

A simple traffic generator for the Ethernet model and the 802.11 model, and generally for any L2 model that accepts Ieee80211Ctrl control info on the packets. It should be connected directly to EtherEncap or an Ieee802NicXXX module.

Used in compound modules

Name	Type	Description
EtherHost2	compound module	An example host with one Ethernet interface and an Ethernet traffic generator directly connected to it. This host model does not contain higher layer protocols (IP, TCP). By default is configured to use half-duplex MAC (CSMA/CD).

Parameters

Name	Type	Default value	Description
destAddress	string	""	destination MAC address, or module path name of destination station; empty means off
etherType	int	0	etherType to set on outgoing packets
startTime	double	this.sendInterval	time of sending the first packet
stopTime	double	-1s	time of finishing sending, negative values mean forever
sendInterval	double		interval between sending bursts
numPacketsPerBurst	int	1	number of packets to send per burst (packets within a burst are sent at the same simulation time)
packetLength	int		length of packets to send

Properties

Name	Value	Description
display	i=block/app

Gates

Name	Direction	Size	Description
in	input
out	output

Signals

Name	Type	Unit
sentPk	cPacket
rcvdPk	cPacket

Statistics

Name	Title	Source	Record	Unit	Interpolation Mode
sentPk	packets sent	sentPk	count, sum(packetBytes), vector(packetBytes)		none
rcvdPk	packets received	rcvdPk	count, sum(packetBytes), vector(packetBytes)		none
endToEndDelay	end-to-end delay	messageAge(rcvdPk)	histogram, vector	s	none
