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 lie
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
LBH2001A Series 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.
Switching, Address Learning
The LBH2001A Series units have address table capacity of 1K node addresses,
and are suitable for use in large networks. They are self-learning, so that as nodes are
added or removed or moved from one segment to another, the LBH2001A Series switch
automatically keeps up with node locations.
