Network Topologies
This section illustrates two network topologies that you can create with
the AT-GS905 Gigabit Ethernet switch: a power workgroup and
collapsed backbone. Both types of topologies are described below.

Workgroup
Topology
The topology shown in Figure 3 is commonly referred to as a power
workgroup topology. Each workstation or end-node is connected
directly to a port on the switch. Each end-node has a dedicated data link
to the switch for best performance and reliability. The devices can
operate at 10 Mbps, 100 Mbps or 1000 Mbps.

Collapsed
Backbone In the topology illustrated in Figure 4, an AT-GS905 switch 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
