Making a Building Resilient to Network Failure

You can build resilience into your building backbone as shown in Figure 5-3. The provision of resilient links protects your network against cable and network failure by using a main and a standby link. Should the main link fail, a standby link automatically takes over the function of the main link.

In this example, the ATM Module fiber link provides the main link in the resilient link pair, and the Fast Ethernet fiber or copper link acts as the standby link.

This configuration ensures that all devices have access to a high-speed backbone connection at all times.
