Collapsed
Backbone - Hub
Topology
In the topology illustrated in Figure 20, an AT-8024 is used to connect
together 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 by 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,
freeing up bandwidth and improving network performance.
