Detailed Description

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

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.

◆ DiscoverLSAs()

uint32_t ns3::GlobalRouter::DiscoverLSAs ( )

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.

◆ DoDispose()

void ns3::GlobalRouter::DoDispose ( )

overrideprivatevirtual

Destructor implementation.

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

Subclasses are expected to implement their real destruction code in an overridden 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:

◆ FindAllNonBridgedDevicesOnLink()

NetDeviceContainer ns3::GlobalRouter::FindAllNonBridgedDevicesOnLink ( Ptr< Channel > ch ) const

private

Return a container of all non-bridged NetDevices on a link.

This method will recursively find all of the 'edge' devices in an L2 broadcast domain. If there are no bridged devices, then the container returned is simply the set of devices on the channel passed in as an argument. If the link has bridges on it (and therefore multiple ns3::Channel objects interconnected by bridges), the method will find all of the non-bridged devices in the L2 broadcast domain.

Parameters

ch	a channel from the link

Returns: the NetDeviceContainer.

◆ FindDesignatedRouterForLink()

Ipv4Address ns3::GlobalRouter::FindDesignatedRouterForLink ( Ptr< NetDevice > ndLocal ) 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

Returns: the IP address of the designated router

Returns: a pointer to that Ipv4RoutingTableEntry is returned

References m_injectedRoutes, NS_ASSERT, and NS_LOG_FUNCTION.

◆ GetLSA()

bool ns3::GlobalRouter::GetLSA	(	uint32_t	n,
		GlobalRoutingLSA &	lsa
	)		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.

References m_injectedRoutes, and NS_LOG_FUNCTION.

◆ GetNumLSAs()

uint32_t ns3::GlobalRouter::GetNumLSAs ( ) const

Get the Number of Global Routing Link State Advertisements that this router can export.

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.

See also: GlobalRouterLSA; GlobalRouting::DiscoverLSAs (); GlobalRouting::GetLSA ()

Returns: The number of Global Routing Link State Advertisements.

The Router IDs are allocated in the RoutingEnvironment – one per Router, starting at 0.0.0.1 and incrementing with each instantiation of a router.
