Collapsed
Backbone

In the topology illustrated in Figure 7, an AT-FS750/48 Fast Ethernet
Smart switch connects switches that have Fast Ethernet uplinks. This type
of topology is often referred to as a collapsed backbone topology. The
switch functions as the focal point of the network and transfers an Ethernet
frame between the Fast Ethernet switches only when the destination end
node for the frame is on a different switch than the end node that
originated the frame. This reduces the amount of unnecessary data traffic
in each workgroup, freeing up bandwidth and improving network
performance.
