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

receive

Description copied from interface: NetInterface.NetHandler

Receive a message from network layer.

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

send

public void send(NetMessage msg)

Description copied from interface: NetInterface.NetHandler

Send a message through the routing protocol
