All Implemented Interfaces:

linkLayer

public class lanLinkLayer

extends com.renesys.raceway.SSF.Entity

implements linkLayer

Implementation of a link layer that performs simple layer 2 routing among a set of two or more attached interfaces. Uses the non-standard NEXT_HOP field in the IP header to identify the channel on which to rebroadcast each received packet.

Constructor Summary

Method Summary

link	onLink() Return a reference to the link for which this is the linkLayer implementation.
java.util.Enumeration	peers(NIC forNIC) Return the attached interfaces that are peers to the given interface.
com.renesys.raceway.SSF.Event[]	receive(NIC forNIC) Poll the link layer for any packets currently available for receipt
void	transmit(NIC forNIC, PacketEvent pevt, long qdelay) Send a packet with the given delay on behalf of the NIC
void	up(NIC nic) Bring up the given NIC over this link layer
