Detailed Description

aggregate Ipv4Linux to nodes

Today the first goal of the Ipv4Linux is to be able to use the standards NS-3 Helpers for two tasks: 1 - assign address to devices using Ipv4AddressHelper, 2 - create the static routes using Ipv4GlobalRoutingHelper

void ns3::LinuxStackHelper::Install ( std::string nodeName )

static

Aggregate ns3::Ipv4Linux classe onto the provided node. This method will assert if called on a node that already has an Ipv4 object aggregated to it.

Parameters

nodeName The name of the node on which to install the stack.

Here is the caller graph for this function:

void ns3::LinuxStackHelper::Install ( Ptr< Node > node )

static

Aggregate ns3::Ipv4Linux classe onto the provided node. This method will assert if called on a node that already has an Ipv4 object aggregated to it.

Parameters

node	The node on which to install the stack.

Here is the call graph for this function:

void ns3::LinuxStackHelper::Install ( NodeContainer c )

static

Aggregate ns3::Ipv4Linux class onto the provided node. This method will assert if called on a node that already has an Ipv4 object aggregated to it.

Parameters

c	NodeContainer that holds the set of nodes on which to install the new stacks.

Here is the call graph for this function:

void ns3::LinuxStackHelper::InstallAll ( void )

static

Aggregate ns3::Ipv4Linux to all nodes in the simulation

Here is the call graph for this function:

void ns3::LinuxStackHelper::PopulateRoutingTables ( )

static

Populate routing information to all the nodes in network from GlobalRoutingTable.

Limitation: 1) This method SHOULD call after Ipv4GlobalRoutingHelper::PopulateRoutingTables () so that LinuxStackHelper can obtain the route information. 2) This feature is only available for IPv4 route information. IPv6 is not implemented.

Here is the call graph for this function:

void ns3::LinuxStackHelper::RunIp	(	Ptr< Node >	node,
		Time	at,
		std::string	str
	)

static

Execute "ip" command (of Linux) on a specific node to configure the ip address/route/etc information.

Parameters

node	The node pointer Ptr<Node> to configure.
at	the delta from the begining of simulation to execute this command.
str	a string for the command line argument of ip command. e.g., "route add 10.0.1.0/24 via 10.0.0.1"

void ns3::LinuxStackHelper::SysctlGet	(	Ptr< Node >	node,
		Time	at,
		std::string	path,
		void(*)(std::string, std::string)	callback
	)

static

Obtain Linux kernel state with traditional 'sysctl' interface.

Parameters

node	The node pointer Ptr<Node> that will ask the status.
at	the delta from the begining of simulation to ask this query.
path	a string value for sysctl parameter. it starts from '.' following the name of parameter. e.g., ".net.ipv4.conf.default.forwarding"
callback	a callback function to parse the result of sysctl query.

Configure Linux kernel parameters with traditional 'sysctl' interface.

Parameters

c	NodeContainer that holds the set of nodes to configure this parameter.
