Collapsed
Backbone
In the topology illustrated in Figure 6, an AT-GS900/8E 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.
