Collapsed
Backbone - Hub
Topology
In the topology illustrated in Figure 21, an AT-8326GB Fast Ethernet
switch is used to connect 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.
