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).

Usage diagram

The following diagram shows usage relationships between types. Unresolved types are missing from the diagram.

Parameters

Name	Type	Default value	Description
csmacdSupport	bool	true	by default use CSMA/CD
fcsMode	string	"declared"

Properties

Name	Value	Description
networkNode
labels	node
display	i=device/pc2

Gates

Name	Direction	Size	Description
ethg	inout

Unassigned submodule parameters

Name	Type	Default value	Description
app.destAddress	string	""	destination MAC address, or module path name of destination station; empty means off
app.ssap	int	-1	llc ssap to set on outgoing packets
app.dsap	int	-1	llc dsap to set on outgoing packets
app.startTime	double	this.sendInterval	time of sending the first packet
app.stopTime	double	-1s	time of finishing sending, negative values mean forever
app.sendInterval	double		interval between sending bursts
app.numPacketsPerBurst	int	1	number of packets to send per burst (packets within a burst are sent at the same simulation time)
app.packetLength	int		length of packets to send
app.stopOperationExtraTime	double	-1s	extra time after lifecycle stop operation finished
app.stopOperationTimeout	double	2s	timeout value for lifecycle stop operation
interfaceTable.displayAddresses	bool	false	whether to display IP addresses on links
