public class LL

extends Module

This class implements some link layer functions. It receives IP packets from the PktDispatcher, encapsulates them in a LLPackets and sends them down to the interface queue. It also receivs InetPacket or ARPPacket from the MAC layer component and passes them to PktDispatcher or ARP components respectively.
