Detailed Description

An interface aggregated to a node to provide global routing info.

Doxygen introspection did not find any typical Config paths.

An interface aggregated to a node that provides global routing information to a global route manager. The presence of the interface indicates that the node is a router. The interface is the mechanism by which the router advertises its connections to neighboring routers. We're basically allowing the route manager to query for link state advertisements.

No Attributes are defined for this type.
No TraceSources are defined for this type.

Member Function Documentation

bool ns3::GlobalRouter::AnotherRouterOnLink	(	Ptr< NetDevice >	nd,
		bool	allowRecursion
	)		const

private

Checks for the presence of another router on the NetDevice.

Given a node and an attached net device, take a look off in the channel to which the net device is attached and look for a node on the other side that has a GlobalRouter interface aggregated. Life gets more complicated when there is a bridged net device on the other side.

Parameters

nd	NetDevice to scan
allowRecursion	Recursively look for routers down bridge port

Returns: true if a router is found

Here is the caller graph for this function:

uint32_t ns3::GlobalRouter::DiscoverLSAs ( void )

Walk the connected channels, discover the adjacent routers and build the associated number of Global Routing Link State Advertisements that this router can export.

This is a fairly expensive operation in that every time it is called the current list of LSAs is built by walking connected point-to-point channels and peeking into adjacent IPV4 stacks to get address information. This is done to allow for limited dynamics of the Global Routing environment. By that we mean that you can discover new link state advertisements after a network topology change by calling DiscoverLSAs and then by reading those advertisements.

See also: GlobalRoutingLSA; GlobalRouter::GetLSA ()

Returns: The number of Global Routing Link State Advertisements.

Here is the call graph for this function:

void ns3::GlobalRouter::DoDispose ( void )

privatevirtual

This method is called by Object::Dispose or by the object's destructor, whichever comes first.

Subclasses are expected to implement their real destruction code in an overriden version of this method and chain up to their parent's implementation once they are done. i.e., for simplicity, the destructor of every subclass should be empty and its content should be moved to the associated DoDispose method.

It is safe to call GetObject from within this method.

Reimplemented from ns3::Object.

Here is the call graph for this function:

Ipv4Address ns3::GlobalRouter::FindDesignatedRouterForLink	(	Ptr< NetDevice >	ndLocal,
		bool	allowRecursion
	)		const

private

Finds a designated router.

Given a local net device, we need to walk the channel to which the net device is attached and look for nodes with GlobalRouter interfaces on them (one of them will be us). Of these, the router with the lowest IP address on the net device connecting to the channel becomes the designated router for the link.

Parameters

ndLocal	local NetDevice to scan
allowRecursion	Recursively look for routers down bridge port

Returns: the IP address of the designated router

bool ns3::GlobalRouter::FindInterfaceForDevice	(	Ptr< Node >	node,
		Ptr< NetDevice >	nd,
		uint32_t &	index
	)		const

private

Given a node and a net device, find an IPV4 interface index that corresponds to that net device.

This function may fail for various reasons. If a node does not have an internet stack (for example if it is a bridge) we won't have an IPv4 at all. If the node does have a stack, but the net device in question is bridged, there will not be an interface associated directly with the device.

Parameters

node	the node
nd	outgoing NetDevice
index	the IPV4 interface index

bool ns3::GlobalRouter::GetLSA	(	uint32_t	n,

	)		const

Get a Global Routing Link State Advertisements that this router has said that it can export.

This is a fairly inexpensive expensive operation in that the hard work was done in GetNumLSAs. We just copy the indicated Global Routing Link State Advertisement into the requested GlobalRoutingLSA object.

You must call GlobalRouter::GetNumLSAs before calling this method in order to discover the adjacent routers and build the advertisements. GetNumLSAs will return the number of LSAs this router advertises. The parameter n (requested LSA number) must be in the range 0 to GetNumLSAs() - 1.

See also: GlobalRoutingLSA; GlobalRouting::GetNumLSAs ()

Parameters

n	The index number of the LSA you want to read.
lsa	The GlobalRoutingLSA class to receive the LSA information.

Returns: The number of Global Router Link State Advertisements.

uint32_t ns3::GlobalRouter::GetNumLSAs ( void ) const

To get meaningful information you must have previously called DiscoverLSAs. After you know how many LSAs are present in the router, you may call GetLSA () to retrieve the actual advertisement.
