Method Detail

dropNotify

public void dropNotify(Message msg,
                       MacAddress nextHopMac,
                       Reason reason)

Notification mechanism for packet dropped due to various "Reasons"

Specified by:

dropNotify in interface NetInterface.NetHandler

send

public void send(NetMessage msg)

This function is called when the App Layer transmits a packet (other than broadcast (NetAddress.ANY) packet) or a message is received from the MAC layer, but, since this node is not the FINAL destination of the message, needs to be forwarded The mechanism is explained in the SIDnet manual. On short: When the app-layer sends a packet down (or link layer sends it UP) to Network layer (unicast) the network layer calls the send(NetMessage) of the routing protocol "indexed" by the packet. Here you decide how to route or what to do with the packet If it is a broadcast packet, the Network layer will immediatelly push the packet DOWN to the Link layer, bypassing the routing protocol

Specified by:

send in interface NetInterface.NetHandler

Specified by:

send in interface RouteInterface

Parameters:

msg - outgoing packet

receive

public void receive(Message msg,
                    NetAddress src,
                    MacAddress lastHop,
                    byte macId,
                    NetAddress dst,
                    byte priority,
                    byte ttl)

Receive a message from the Link layer This function is called whenever the link layer receives a message whose final destination is THIS node.

Specified by:

receive in interface NetInterface.NetHandler

Parameters:

msg - message received

src - source network address

lastHop - source link address

macId - incoming interface

dst - destination network address

priority - packet priority

ttl - packet time-to-live

peek

public void peek(NetMessage msg,
                 MacAddress lastHopMac)

Description copied from interface: RouteInterface

Called by the network layer for every incoming packet. A routing implementation may wish to look at these packets for informational purposes, but should not change their contents.

Specified by:

peek in interface RouteInterface

Parameters:

msg - incoming packet

lastHopMac - last link-level hop of incoming packet

sendToLinkLayer

public byte sendToLinkLayer(NetMessage.Ip ipMsg,
                            NetAddress nextHopDestIP)

convenience function to send data DOWN ("to link layer")

sendToAppLayer

public void sendToAppLayer(Message msg,
                           NetAddress src)

convenience function to send data UP ("to app layer")

internals - for hooking up with App-Layer

setNetEntity

public void setNetEntity(NetInterface netEntity)
