CentreCOM AT-3675 SNMP-Manageable Learning Bridge

Simple Bridged Network. In many cases, workgroup boundaries are

clearly deﬁned and it is obvious where to place the bridges. This is especially

true for small organizations, which will only use one or two bridges or when

previously separate networks are being interconnected. Figure 8 below

shows this kind of conﬁguration.

Analysis of Large Networks. When a large existing network is broken up

into smaller networks, it is useful to perform a thorough analysis of the

network trafﬁc patterns. With the aid of a network monitor, you can

determine the amount of trafﬁc between nodes throughout the network.

Workgroup boundaries (or natural cluster boundaries) exist at the points

where the smallest amount of trafﬁc passes. Bridges should always be placed

at these points of minimal trafﬁc.

For example, consider the network shown in Figure 9. This network of four

nodes exhibits trafﬁc patterns listed in Table 6.
