AT-8500 Series Layer 2+ Fast Ethernet Switches Installation Guide

Network Topologies

This section illustrates several of the network topologies you can create

with the AT-8500 Series Fast Ethernet switch.

Power

Workgroup

Topology

The topology shown in Figure 9 is commonly referred to as a power

workgroup topology. Each workstation or end node is connected directly to

a port on an AT-8524M Fast Ethernet Switch. This provides each end

node with a dedicated data link to the switch for best performance and

reliability. The devices can operate at either 10 Mbps or 100 Mbps.

Backbone

Topology

In the topology illustrated in Figure 10, an AT-8524M Fast Ethernet Switch

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.
