Method Detail

peek

void peek(NetMessage msg,
          MacAddress lastHop)

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.

Parameters:

msg - incoming packet

lastHop - last link-level hop of incoming packet

send

void send(NetMessage msg)

Called by the network layer to request transmission of a packet that requires routing. It is the responsibility of the routing layer to provide a best-effort transmission of this packet to an appropriate next hop by calling the network layer sending routines once this routing information becomes available.

Parameters:

msg - outgoing packet
