Collapsed

Backbone

In the topology illustrated in Figure 5, an AT-GS900/16 switch 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 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.
