EtherTrafGen

simple module

A simple traffic generator for the Ethernet model and the 802.11 model, and generally for any L2 model that accepts ~Ieee802SapReq tag on packets. It should be connected directly to ~Ieee8022Llc module.

Parameters

Name	Type	Default value	Description
destAddress	string	""	destination MAC address, or module path name of destination station; empty means off
interface	string		outgoing interface
interfaceTableModule	string
ssap	int	-1	llc ssap to set on outgoing packets
dsap	int	-1	llc dsap 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
stopOperationExtraTime	double	-1s	extra time after lifecycle stop operation finished
stopOperationTimeout	double	2s	timeout value for lifecycle stop operation

Properties
