EtherAppClient

simple module

A simple traffic generator for the Ethernet model and the 802.11 model, and generally for any L2 model that accepts Ieee802SapReq tags on the packets. It generates packets containing EtherAppReq chunks. It should be connected directly to EtherEncap/Ieee8022Llc.

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	local service access point
remoteSAP	int	0xf1	remote service access point
sendInterval	double	uniform(0s,1s)	interval between sending requests
reqLength	int	100B	length of request packets
respLength	int	1KiB	length of response packets
stopOperationExtraTime	double	-1s	extra time after lifecycle stop operation finished
stopOperationTimeout	double	2s	timeout value for lifecycle stop operation

Properties

Name	Value	Description
lifecycleSupport
display	i=block/app

Gates

Name	Direction	Size	Description
in	input
out	output

Signals

Name	Type	Unit
packetReceived	inet::Packet
packetSent	inet::Packet

Statistics

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