Collapsed Backbone

AT-GS900/16, AT-GS900/24 Fanless Gigabit Ethernet Switches Installation Guide

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.
