AT-GS908 Gigabit Ethernet Switch Installation Guide

Collapsed

Backbone

In the topology illustrated in Figure 4, an AT-GS908 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.
