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.
HardwareFrame	forwardDataPacket(NormalPacketHeader toForward, HardwareFrame in)
int	getAddress() getAddress()
java.util.LinkedList<HardwareFrame>	getDataCache()
RouteCache	getRouteCache()
void	newPacket(Node dest, Packet packet) Event when a Node wants to send a new Packet.
void	routeRepair(int source, int destination, int sequenceNumber, int forwardCount, int lastKnownDistance, Packet packetTryingToSend) routeRepair() will send out RREQ to see if it can get a new path for the packet.
void	sendRERR(int source, int destination, int sequenceNumber, int previousHop)
void	terminated(HardwareFrame in) terminated will basically sent an ack back it it receives a packet

Method Detail

forwardDataPacket

public HardwareFrame forwardDataPacket(NormalPacketHeader toForward,
                                       HardwareFrame in)

sendRERR

public void sendRERR(int source,
                     int destination,
                     int sequenceNumber,
                     int previousHop)

terminated

public void terminated(HardwareFrame in)

terminated will basically sent an ack back it it receives a packet

Specified by:

terminated in interface RoutingAlgorithm

Overrides:

terminated in class AbstractRoutingAlgorithm

Parameters:

in - non-null HardwareFrame received

arrived

public void arrived(HardwareFrame in)

Description copied from class: AbstractRoutingAlgorithm

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

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.

routeRepair

public void routeRepair(int source,
                        int destination,
                        int sequenceNumber,
                        int forwardCount,
                        int lastKnownDistance,
                        Packet packetTryingToSend)

routeRepair() will send out RREQ to see if it can get a new path for the packet.

Parameters:

source, -

destination -

sequenceNumber -

forwardCount -

lastKnownDistance -

propagationRange -

packetTryingToSend -

getAddress

public int getAddress()

getAddress()

Returns:

address of node

getRouteCache

public RouteCache getRouteCache()

getDataCache

public java.util.LinkedList<HardwareFrame> getDataCache()
