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().

Reimplemented from ns3::Object.

Reimplemented in ns3::aodv::RoutingProtocol, ns3::dsdv::RoutingProtocol, ns3::Ipv4GlobalRouting, ns3::Ipv4ListRouting, ns3::Ipv4NixVectorRouting, ns3::olsr::RoutingProtocol, and ns3::Ipv4StaticRouting.

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

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

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.

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

virtual void ns3::Ipv4RoutingProtocol::NotifyRemoveAddress ( 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 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::aodv::RoutingProtocol, ns3::dsdv::RoutingProtocol, ns3::Ipv4GlobalRouting, ns3::Ipv4ListRouting, and ns3::Ipv4StaticRouting.

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:
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::aodv::RoutingProtocol, ns3::Ipv4GlobalRouting, ns3::Ipv4ListRouting, and ns3::Ipv4StaticRouting.

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:
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

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

virtual void ns3::Ipv4RoutingProtocol::SetIpv4 ( Ptr< Ipv4 >  ipv4  )  [pure virtual]
Parameters:
ipv4 the ipv4 object this routing protocol is being associated with

Typically, invoked directly or indirectly from ns3::Ipv4::SetRoutingProtocol

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