Collapsed Backbone

In the topology illustrated in Figure 7, an AT-9424T/SP Gigabit Ethernet Switch forms the backbone that connects to servers and AT-FS750/ 24POE Fast Ethernet Smart switches using 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.
