Networks:

LargeNet (network)

A large Ethernet LAN -- see model description here.

Parameters:

Name	Type	Default value	Description
n	int		number of hosts on the switch
h	int		number of hosts on the hub

Properties:

Name	Value	Description
display	i=cloud_s

Gates:

Name	Direction	Size	Description
ethg	inout

Unassigned submodule parameters:

Name	Type	Default value	Description
switch.relayUnit.addressTableFile	string		set to empty string if not used
switch.relayUnit.addressTableSize	int		max size of address table
switch.relayUnit.agingTime	double		max idle time for address table entries (when it expires, entry is removed from the table)
switch.mac.address	string	"auto"	MAC address as hex string (12 hex digits), or "auto". "auto" values will be replaced by a generated MAC address in init stage 0.
switch.mac.txrate	double	100Mbps	maximum data rate supported by this station (bit/s); actually chosen speed may be lower due to auto- configuration. 0 means fully auto-configured.
switch.mac.duplexEnabled	bool	true	whether duplex mode can be enabled or not; whether MAC will actually use duplex mode depends on the result of the auto-configuration process (duplex is only possible with DTE-to-DTE connection).
switch.mac.txQueueLimit	int	1000	maximum number of frames queued up for transmission; additional frames are dropped. Only used if queueModule==""
switch.mac.mtu	int	1500
host.cli.destAddress	string	""	destination MAC address, or module path name of destination station; empty means off
host.cli.startTime	double	this.waitTime	time of sending the first request
host.cli.waitTime	double	uniform(0s,1s)	interval between sending requests
host.cli.reqLength	int	100B	length of request packets
host.cli.respLength	int	1KB	length of response packets
host.mac.promiscuous	bool	false	if true, all packets are received, otherwise only the ones with matching destination MAC address
host.mac.address	string	"auto"	MAC address as hex string (12 hex digits), or "auto". "auto" values will be replaced by a generated MAC address in init stage 0.
host.mac.txrate	double	100Mbps	maximum data rate supported by this station (bit/s); actually chosen speed may be lower due to auto- configuration. 0 means fully auto-configured.
host.mac.duplexEnabled	bool	true	whether duplex mode can be enabled or not; whether MAC will actually use duplex mode depends on the result of the auto-configuration process (duplex is only possible with DTE-to-DTE connection).
host.mac.txQueueLimit	int	1000	maximum number of frames queued up for transmission; additional frames are dropped. Only used if queueModule==""
host.mac.mtu	int	1500
hhost.cli.destAddress	string	""	destination MAC address, or module path name of destination station; empty means off
hhost.cli.startTime	double	this.waitTime	time of sending the first request
hhost.cli.waitTime	double	uniform(0s,1s)	interval between sending requests
hhost.cli.reqLength	int	100B	length of request packets
hhost.cli.respLength	int	1KB	length of response packets
hhost.mac.promiscuous	bool	false	if true, all packets are received, otherwise only the ones with matching destination MAC address
hhost.mac.address	string	"auto"	MAC address as hex string (12 hex digits), or "auto". "auto" values will be replaced by a generated MAC address in init stage 0.
