Introduction
Theory of Operation
Ethernet segment switches divide a large local network into smaller
segments, insulating each from the other's local traffic and increasing
aggregate bandwidth, while still retaining full connectivity. The AT-
8116 is designed to be self-configuring and extremely fast, making
installation simple and providing an increase in available bandwidth.
The switch learns on which port stations are located by remembering
the source address of every packet received on every port. When
packets are received for stations that the switch has learned, they will
be forwarded to only the port on which the station is located. This is in
contrast to a hub, which sends every packet to every port.
If the switch receives a packet addressed to a station which the switch
has not learned, the packet is sent to every port, except the port on
which it was received, just as a hub would. This insures that full
connectivity is maintained. The high port density of the AT-8116 allows
for dedicated high-performance workstation links.
