Collapsed
Backbone In the topology illustrated in Figure 6, an AT-GS924GB connects Fast
Ethernet switches that have Gigabit 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 node for the frame is on a different switch than the node
that originated the frame. This reduces the amount of unnecessary data
traffic in each workgroup, freeing up bandwidth and improving network
performance.
