void ns3::aodv::RoutingProtocol::DoDispose ( void )

virtual

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.

	)

virtual

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

	)

virtual

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
