Parameters:

	filename	filename prefix to use for pcap files.
	nodeid	the id of the node to generate pcap output for.
	deviceid	the id of the device to generate pcap output for.

Generate a pcap file which contains the link-level data observed by the specified deviceid within the specified nodeid. The pcap data is stored in the file prefix-nodeid-deviceid.pcap.

This method should be invoked after the network topology has been fully constructed.

		NetDeviceContainer	d
	)			`[static]`

Parameters:

	filename	filename prefix to use for pcap files.
	d	container of devices of type ns3::CsmaNetDevice

Enable pcap output on each input device which is of the ns3::CsmaNetDevice type.

static void ns3::CsmaHelper::EnablePcapAll ( std::string filename ) [static]

Parameters:

filename

filename prefix to use for pcap files.

Enable pcap output on each device which is of the ns3::CsmaNetDevice type

NetDeviceContainer ns3::CsmaHelper::Install ( const NodeContainer & c ) const

This method creates an ns3::CsmaChannel with the attributes configured by CsmaHelper::SetChannelAttribute. For each Ptr<node> in the provided container: it creates an ns3::CsmaNetDevice (with the attributes configured by CsmaHelper::SetDeviceAttribute); adds the device to the node; and attaches the channel to the device.

Parameters:

c

The NodeContainer holding the nodes to be changed.

Returns:: A containter holding the added net devices.

NetDeviceContainer ns3::CsmaHelper::Install	(	const NodeContainer &	c,
		Ptr< CsmaChannel >	channel
	)			const

For each Ptr<node> in the provided container, this method creates an ns3::CsmaNetDevice (with the attributes configured by CsmaHelper::SetDeviceAttribute); adds the device to the node; and attaches the provided channel to the device.

Parameters:

	c	The NodeContainer holding the nodes to be changed.
	channel	The channel to attach to the devices.

Returns:: A containter holding the added net devices.

NetDeviceContainer ns3::CsmaHelper::Install ( Ptr< Node > node ) const

This method creates an ns3::CsmaChannel with the attributes configured by CsmaHelper::SetChannelAttribute, an ns3::CsmaNetDevice with the attributes configured by CsmaHelper::SetDeviceAttribute and then adds the device to the node and attaches the channel to the device.

Parameters:

node

The node to install the device in

Returns:: A containter holding the added net device.

NetDeviceContainer ns3::CsmaHelper::Install	(	Ptr< Node >	node,
		Ptr< CsmaChannel >	channel
	)			const

This method creates an ns3::CsmaNetDevice with the attributes configured by CsmaHelper::SetDeviceAttribute and then adds the device to the node and attaches the provided channel to the device.

Parameters:

	node	The node to install the device in
	channel	The chanel to attach to the device.

Returns:: A containter holding the added net device.

void ns3::CsmaHelper::InstallStar	(	Ptr< Node >	hub,
		NodeContainer	spokes,
		NetDeviceContainer &	hubDevices,
		NetDeviceContainer &	spokeDevices
	)

Make a star network topology.

Given a pointer to a node that will become the hub of the star, and a NodeContainer containing pointers to the nodes that will become the spokes; we construct CSMA net devices on the hub (corresponding to the spokes) and store them in the hubDevices NetDeviceContainer. We add a net device to each spoke node and store them in the spokeDevices NetDeviceContainer. A CSMA is created for each spoke.

Usually when one thinks of a star network, one thinks of point-to-point links. We're just using a single pair of devices on a multi-point-to-point network "drops" as the link. You are free to add any number of other devices on the link if you want.

The ordering of the devices in the hubDevices container is according to the order of the spokes container -- that is, hubDevices[0] will be the net device used on the hub that talks to spokes[0]. the container entry spokeDevices[0] will have the device that hubDevices[0] talks to -- those two devices are the ones that connect hub to spokes[0].

Parameters:

	hub	The central node of the star network
	spokes	A NodeContainer of the nodes that will be the spoke (leaf) nodes
	hubDevices	A NetDeviceContainer that will be filled with pointers to the point-to-point net devices created on the hub.
	spokeDevices	A NetDeviceContainer that will be filled with pointers to the point-to-point net devices created on each of the spokes.

void ns3::CsmaHelper::SetChannelAttribute	(	std::string	n1,
		const AttributeValue &	v1

Set these attributes on each ns3::CsmaChannel created by CsmaHelper::Install

void ns3::CsmaHelper::SetDeviceAttribute	(	std::string	n1,
		const AttributeValue &	v1
	)

Parameters:

Set these attributes on each ns3::CsmaNetDevice created by CsmaHelper::Install
