Detailed Description

Abstract base class for IPv4 routing protocols.

Defines two virtual functions for packet routing and forwarding. The first, RouteOutput(), is used for locally originated packets, and the second, RouteInput(), is used for forwarding and/or delivering received packets. Also defines the signatures of four callbacks used in RouteInput().

Here is the call graph for this function:

virtual void ns3::Ipv4RoutingProtocol::NotifyAddAddress	(	uint32_t	interface,
		Ipv4InterfaceAddress	address
	)

pure virtual

Parameters

interface	the index of the interface we are being notified about
address	a new address being added to an interface

Protocols are expected to implement this method to be notified whenever a new address is added to an interface. Typically used to add a 'network route' on an interface. Can be invoked on an up or down interface.

Implemented in ns3::Ipv4GlobalRouting, ns3::Ipv4ListRouting, ns3::Ipv4StaticRouting, ns3::dsdv::RoutingProtocol, ns3::aodv::RoutingProtocol, ns3::Ipv4BRouting, and ns3::Ipv4ARouting.

Here is the caller graph for this function:

virtual void ns3::Ipv4RoutingProtocol::NotifyInterfaceDown ( uint32_t interface )

pure virtual

Parameters

interface the index of the interface we are being notified about

Protocols are expected to implement this method to be notified of the state change of an interface in a node.

Implemented in ns3::Ipv4GlobalRouting, ns3::Ipv4ListRouting, ns3::Ipv4StaticRouting, ns3::dsdv::RoutingProtocol, ns3::aodv::RoutingProtocol, ns3::Ipv4BRouting, and ns3::Ipv4ARouting.

Here is the caller graph for this function:

virtual void ns3::Ipv4RoutingProtocol::NotifyInterfaceUp ( uint32_t interface )

pure virtual

Parameters

interface the index of the interface we are being notified about

Protocols are expected to implement this method to be notified of the state change of an interface in a node.

		Ipv4InterfaceAddress	address
	)

pure virtual

Parameters

interface	the index of the interface we are being notified about
address	a new address being added to an interface

Protocols are expected to implement this method to be notified whenever a new address is removed from an interface. Typically used to remove the 'network route' of an interface. Can be invoked on an up or down interface.

Implemented in ns3::Ipv4GlobalRouting, ns3::Ipv4ListRouting, ns3::Ipv4StaticRouting, ns3::dsdv::RoutingProtocol, ns3::aodv::RoutingProtocol, ns3::Ipv4BRouting, and ns3::Ipv4ARouting.

Parameters

stream the ostream the Routing table is printed to

		const Ipv4Header &	header,
		Ptr< const NetDevice >	idev,
		UnicastForwardCallback	ucb,
		MulticastForwardCallback	mcb,
		LocalDeliverCallback	lcb,
		ErrorCallback	ecb
	)

pure 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

Implemented in ns3::Ipv4GlobalRouting, ns3::Ipv4ListRouting, ns3::Ipv4StaticRouting, ns3::aodv::RoutingProtocol, ns3::Ipv4BRouting, and ns3::Ipv4ARouting.

Referenced by ns3::Ipv4L3Protocol::Receive().

Here is the caller graph for this function:

virtual Ptr<Ipv4Route> ns3::Ipv4RoutingProtocol::RouteOutput	(	Ptr< Packet >	p,
		const Ipv4Header &	header,
		Ptr< NetDevice >	oif,
		Socket::SocketErrno &	sockerr
	)

pure 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
