Detailed Description

The Link State DataBase (LSDB) of the Global Route Manager.

Each node in the simulation participating in global routing has a GlobalRouter interface. The primary job of this interface is to export Global Router Link State Advertisements (LSAs). These advertisements in turn contain a number of Global Router Link Records that describe the point to point links from the underlying node to other nodes (that will also export their own LSAs.

This class implements a searchable database of LSAs gathered from every router in the simulation.

Constructor & Destructor Documentation

ns3::GlobalRouteManagerLSDB::GlobalRouteManagerLSDB ( )

Construct an empty Global Router Manager Link State Database.

The database map composing the Link State Database is initialized in this constructor.

Definition at line 416 of file global-route-manager-impl.cc.

References NS_LOG_FUNCTION.

ns3::GlobalRouteManagerLSDB::~GlobalRouteManagerLSDB ( )

Destroy an empty Global Router Manager Link State Database.

The database map is walked and all of the Link State Advertisements stored in the database are freed; then the database map itself is clear ()ed to release any remaining resources.

Member Function Documentation

GlobalRoutingLSA * ns3::GlobalRouteManagerLSDB::GetLSA ( Ipv4Address addr ) const

Look up the Link State Advertisement associated with the given link state ID (address).

The database map is searched for the given IPV4 address and corresponding GlobalRoutingLSA is returned.

See Also: GlobalRoutingLSA; Ipv4Address

Parameters

addr	The IP address associated with the LSA. Typically the Router ID.

Returns: A pointer to the Link State Advertisement for the router specified by the IP address addr.

GlobalRoutingLSA * ns3::GlobalRouteManagerLSDB::GetLSAByLinkData ( Ipv4Address addr ) const

Look up the Link State Advertisement associated with the given link state ID (address). This is a variation of the GetLSA call to allow the LSA to be found by matching addr with the LinkData field of the TransitNetwork link record.

See Also: GetLSA

Parameters

addr	The IP address associated with the LSA. Typically the Router

Returns: A pointer to the Link State Advertisement for the router specified by the IP address addr. ID.

void ns3::GlobalRouteManagerLSDB::Initialize ( void )

Set all LSA flags to an initialized state, for SPF computation.

This function walks the database and resets the status flags of all of the contained Link State Advertisements to LSA_SPF_NOT_EXPLORED. This is done prior to each SPF calculation to reset the state of the SPFVertex structures that will reference the LSAs during the calculation.

void ns3::GlobalRouteManagerLSDB::Insert	(	Ipv4Address	addr,
		GlobalRoutingLSA *	lsa
	)

Insert an IP address / Link State Advertisement pair into the Link State Database.

The IPV4 address and the GlobalRoutingLSA given as parameters are converted to an STL pair and are inserted into the database map.

See Also: GlobalRoutingLSA; Ipv4Address

Parameters

addr	The IP address associated with the LSA. Typically the Router ID.
lsa	A pointer to the Link State Advertisement for the router.
