Member Function Documentation

◆ AssignIpv4Addresses()

void ns3::PointToPointGridHelper::AssignIpv4Addresses	(	Ipv4AddressHelper	rowIp,
		Ipv4AddressHelper	colIp )

Assigns Ipv4 addresses to all the row and column interfaces.

Parameters

rowIp	the Ipv4AddressHelper used to assign Ipv4 addresses to all of the row interfaces in the grid
colIp	the Ipv4AddressHelper used to assign Ipv4 addresses to all of the column interfaces in the grid

Here is the call graph for this function:

◆ AssignIpv6Addresses()

void ns3::PointToPointGridHelper::AssignIpv6Addresses	(	Ipv6Address	network,
		Ipv6Prefix	prefix )

Assigns Ipv6 addresses to all the row and column interfaces.

Parameters

network	an IPv6 address representing the network portion of the IPv6 Address
prefix	the prefix length

Here is the call graph for this function:

◆ BoundingBox()

void ns3::PointToPointGridHelper::BoundingBox	(	double	ulx,
		double	uly,
		double	lrx,
		double	lry )

Sets up the node canvas locations for every node in the grid.

This is needed for use with the animation interface

Parameters

ulx	upper left x value
uly	upper left y value
lrx	lower right x value
lry	lower right y value

Here is the call graph for this function:

◆ GetIpv4Address()

Ipv4Address ns3::PointToPointGridHelper::GetIpv4Address	(	uint32_t	row,
		uint32_t	col )

This returns an Ipv4 address at the node specified by the (row, col) address.

Technically, a node will have multiple interfaces in the grid; therefore, it also has multiple Ipv4 addresses. This method only returns one of the addresses. If you picture the grid, the address returned is the left row device of all the nodes, except the left-most grid nodes, which returns the right row device.

Parameters

row	the row address of the node desired
col	the column address of the node desired

Returns: Ipv4Address of one of the interfaces of the node specified by the (row, col) address

Definition at line 234 of file point-to-point-grid.cc.

◆ GetIpv6Address()

Ipv6Address ns3::PointToPointGridHelper::GetIpv6Address	(	uint32_t	row,
		uint32_t	col )

This returns an Ipv6 address at the node specified by the (row, col) address.

Technically, a node will have multiple interfaces in the grid; therefore, it also has multiple Ipv6 addresses. This method only returns one of the addresses. If you picture the grid, the address returned is the left row device of all the nodes, except the left-most grid nodes, which returns the right row device.

Parameters

row	the row address of the node desired
col	the column address of the node desired

Returns: Ipv6Address of one of the interfaces of the node specified by the (row, col) address

◆ GetNode()

Ptr< Node > ns3::PointToPointGridHelper::GetNode	(	uint32_t	row,
		uint32_t	col )

Parameters

row	the row address of the node desired
col	the column address of the node desired

Returns: a pointer to the node specified by the (row, col) address
