In the topology illustrated in Figure 4, an AT-FS709FC is used to connect
together eight 10/100 Mbps Ethernet hubs. This type of topology is often
referred to as a collapsed backbone topology. The switch functions as the focal
point for all workgroup hubs in your network, acting as a bridge between the
different workgroups. The switch transfers an Ethernet frame from hub to
hub only when the destination node for the frame is on a different hub than
the node that originated the frame. This reduces the amount of unnecessary
data traffic in each workgroup, which frees up bandwidth and improves
network performance.
