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.
