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().

virtual void ns3::Ipv4RoutingProtocol::NotifyAddAddress ( uint32_t  interface,
Ipv4InterfaceAddress  address 
)
pure virtual
Parameters:
interfacethe index of the interface we are being notified about
addressa 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, and ns3::aodv::RoutingProtocol.

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

virtual void ns3::Ipv4RoutingProtocol::NotifyInterfaceDown ( uint32_t  interface)
pure virtual
Parameters:
interfacethe 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, and ns3::aodv::RoutingProtocol.

virtual void ns3::Ipv4RoutingProtocol::NotifyInterfaceUp ( uint32_t  interface)
pure virtual
Parameters:
interfacethe 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, and ns3::aodv::RoutingProtocol.

virtual void ns3::Ipv4RoutingProtocol::NotifyRemoveAddress ( uint32_t  interface,
Ipv4InterfaceAddress  address 
)
pure virtual
Parameters:
interfacethe index of the interface we are being notified about
addressa 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, and ns3::aodv::RoutingProtocol.

virtual void ns3::Ipv4RoutingProtocol::PrintRoutingTable ( Ptr< OutputStreamWrapper stream) const
pure virtual

Print the Routing Table entries.

Parameters:
streamthe ostream the Routing table is printed to

virtual bool ns3::Ipv4RoutingProtocol::RouteInput ( Ptr< const Packet p,
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:
preceived packet
headerinput parameter used to form a search key for a route
idevPointer to ingress network device
ucbCallback for the case in which the packet is to be forwarded as unicast
mcbCallback for the case in which the packet is to be forwarded as multicast
lcbCallback for the case in which the packet is to be locally delivered
ecbCallback 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, and ns3::aodv::RoutingProtocol.

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()

Parameters:
ppacket to be routed. Note that this method may modify the packet. Callers may also pass in a null pointer.
headerinput parameter (used to form key to search for the route)
oifOutput interface Netdevice. May be zero, or may be bound via socket options to a particular output interface.
sockerrOutput parameter; socket errno
Returns:
a code that indicates what happened in the lookup

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

pure virtual
Parameters:
