Chapter 2 — Connecting to the Network
A Simple Transparent Bridge
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:
