Collapsed
Backbone
In the topology illustrated in Figure 5, an AT-GS950/48 Gigabit Ethernet
Smart 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.
