Collapsed
In the topology illustrated in Figure 5, an AT-GS916 switch connects Fast
Ethernet switches that have Gigabit Ethernet uplinks. This type of
Backbone
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.
