Chapter 2 — Connecting to the Network
The more hubs and users added, the more traffic occurs on the
backbone, until we eventually reach a point at which overall net-
work performance begins to degrade. As a general rule, bridges
are typically required when users begin to complain that response
times are too great or file transfers are too slow. These symptoms
are usually seen when overall utilization exceeds 40% on a regular
basis. Now it is time to split the net into two segments and add a
bridge between them. Logically, the net will look like this:
