void ns3::olsr::RoutingProtocol::DoInitialize ( )

overrideprotectedvirtual

Initialize() implementation.

This method is called only once by Initialize(). If the user calls Initialize() multiple times, DoInitialize() is called only the first time.

Subclasses are expected to override this method and chain up to their parent's implementation once they are done. It is safe to call GetObject() and AggregateObject() from within this method.

Reimplemented from ns3::Object.

◆ FindSendEntry()

bool ns3::olsr::RoutingProtocol::FindSendEntry	(	const RoutingTableEntry &	entry,
		RoutingTableEntry &	outEntry ) const

private

Finds the appropriate entry which must be used in order to forward a data packet to a next hop (given a destination).

Imagine a routing table like this: [A,B] [B,C] [C,C]; being each pair of the form [dest addr, next-hop addr]. In this case, if this function is invoked with [A,B] then pair [C,C] is returned because C is the next hop that must be used to forward a data packet destined to A. That is, C is a neighbor of this node, but B isn't. This function finds the appropriate neighbor for forwarding a packet.

Parameters

[in]	entry	The routing table entry which indicates the destination node we are interested in.
[out]	outEntry	The appropriate routing table entry which indicates the next hop which must be used for forwarding a data packet, or NULL if there is no such entry.

Returns: True if an entry was found, false otherwise.

private

See RFC 3626 for details.

Parameters

		const UnicastForwardCallback &	ucb,
		const MulticastForwardCallback &	mcb,
		const LocalDeliverCallback &	lcb,
		const ErrorCallback &	ecb )

overridevirtual

Route an input packet (to be forwarded or locally delivered)

This lookup is used in the forwarding process. The packet is handed over to the Ipv4RoutingProtocol, and will get forwarded onward by one of the callbacks. The Linux equivalent is ip_route_input(). There are four valid outcomes, and a matching callbacks to handle each.

Parameters

p	received packet
header	input parameter used to form a search key for a route
idev	Pointer to ingress network device
ucb	Callback for the case in which the packet is to be forwarded as unicast
mcb	Callback for the case in which the packet is to be forwarded as multicast
lcb	Callback for the case in which the packet is to be locally delivered
ecb	Callback to call if there is an error in forwarding

Returns: true if the Ipv4RoutingProtocol takes responsibility for forwarding or delivering the packet, false otherwise

		const Ipv4Header &	header,

overridevirtual

Query routing cache for an existing route, for an outbound packet.

This lookup is used by transport protocols. It does not cause any packet to be forwarded, and is synchronous. Can be used for multicast or unicast. The Linux equivalent is ip_route_output()

The header input parameter may have an uninitialized value for the source address, but the destination address should always be properly set by the caller.

Parameters

p	packet to be routed. Note that this method may modify the packet. Callers may also pass in a null pointer.
header	input parameter (used to form key to search for the route)
oif	Output interface Netdevice. May be zero, or may be bound via socket options to a particular output interface.
sockerr	Output parameter; socket errno

Returns: a code that indicates what happened in the lookup
