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).

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
macType	string	csmacdSupport ? "EtherMAC" : "EtherMACFullDuplex"	EtherMAC or EtherMACFullDuplex
queueType	string	""	DropTailQueue, DiffServQueue, or "" to use the internal queue

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.etherType	int	0	etherType 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
queue.pauseQueue.frameCapacity	int	100
mac.promiscuous	bool		if true, all packets are received, otherwise only the ones with matching destination MAC address
mac.address	string		MAC address as hex string (12 hex digits), or "auto". "auto" values will be replaced by a generated MAC address in init stage 0.
mac.duplexMode	bool		selects full-duplex (true) or half-duplex (false) operation
mac.txQueueLimit	int		maximum number of frames queued up for transmission; additional frames are dropped. Only used if queueModule==""
mac.mtu	int
