Network Topologies

This section describes the network topologies of the AT-GS950/8POE
Gigabit Ethernet WebSmart Switch: power workgroup and collapsed
backbone. Both types of topologies are described in the following
sections.

Topology

The topology shown in Figure 4 is commonly referred to as a power
workgroup topology. This topology provides the best performance and
reliability because each end node is connected directly to the AT-GS950/
8POE switch with a dedicated network link.

Collapsed
Backbone

In the topology illustrated in Figure 5 on page 31, the AT-GS950/8POE
switch is connected to managed and unmanaged Ethernet switches to
form a collapsed backbone topology. The AT-GS950/8POE switch
functions as the focal point of the network by transferring Ethernet frames
between switches. This topology reduces the amount of unnecessary
traffic in each workgroup, because the AT-GS950/8POE switch transfers
frames only when the source and destination end nodes are located on
different switches. This frees up bandwidth and improves network
performance.
