Switching, Filtering and Forwarding
Each time a packet arrives on one of the switched ports, the decision is taken to
either filter or to forward the packet. Packets whose source and destination addresses on
the same port segment will be filtered, constraining them to one port and relieving the rest
of the network from processing them. A packet whose destination address is on another
port segment will be forwarded to the appropriate port, and will not be sent to the other
ports where it is not needed. Packets needed for maintaining the operation of the network
(such as occasional multi-cast packets) are forwarded to all ports. The LBH100A and
LBH110A Series Media Converter Switches operate in the store-and-forward switching
mode, which eliminates bad packets and enables peak performance to be achieved when
there is heavy traffic on the network.
