EtherAppCli

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 generates EtherAppReq packets. It should be connected directly to EtherLLC or a Ieee802NicXXX module.

Used in compound modules

Name	Type	Description
EtherHost	compound module	An example host with one Ethernet port and a traffic generator that generates request-reply traffic directly over Ethernet. This host model does not contain higher layer protocols (IP, TCP). By default it 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
startTime	double	this.sendInterval	time of sending the first request
stopTime	double	-1s	time of finishing sending, negative values mean forever
localSAP	int	0xf0
remoteSAP	int	0xf1
sendInterval	double	uniform(0s,1s)	interval between sending requests
reqLength	int	100B	length of request packets
respLength	int	1KiB	length of response packets
registerSAP	bool	false	whether to sent IEEE802CTRL_REGISTER_DSAP on startup

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
