Class FloodingRoutingAlgorithm

java.lang.Object
  Sim.Routing.AbstractRoutingAlgorithm
      Sim.Routing.FloodingRoutingAlgorithm

All Implemented Interfaces:

RoutingAlgorithm

public class FloodingRoutingAlgorithm
extends AbstractRoutingAlgorithm

FloodingRoutingAlgorithm implements a simple routing algorithm where every user data packet is flooded to all nodes. A cache of seen packets prevents reflooding of the same packet (which prevents loops in the routing).

Method Summary

void	arrived(HardwareFrame in) Event when a HardwareFrame arrives destined for this Node that does not have a user Packet, or has a Packet not for this Node.
void	newPacket(Node dest, Packet packet) Event when a Node wants to send a new Packet.

Method Detail

newPacket

public void newPacket(Node dest,
                      Packet packet)

Event when a Node wants to send a new Packet. The RoutingAlgorithm should bundle the Packet in a HardwareFrame and send it through the Node.

Specified by:

newPacket in interface RoutingAlgorithm

Overrides:

newPacket in class AbstractRoutingAlgorithm

Parameters:

dest - non-null Node as the destination (packet.getDest() == dest.getAddress())

packet - user packet data to send, with a destination address not equal to the address for the sending Node.

arrived

public void arrived(HardwareFrame in)

Event when a HardwareFrame arrives destined for this Node that does not have a user Packet, or has a Packet not for this Node. The data in the frame may need to be routed.

Specified by:

arrived in interface RoutingAlgorithm

Overrides:

arrived in class AbstractRoutingAlgorithm

Parameters:

in - non-null HardwareFrame received
