Collapsed
Backbone - Hub
Topology
In the topology illustrated in Figure 15, an AT-8024 connects 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
of the network by acting as a bridge between the different workgroups.
The switch transfers an Ethernet frame from hub to hub only when the
destination end-node for the frame is on a different hub 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.
