Resilience

You can make your network more robust by adding resilience to it.

When a link fails, as shown in Figure 4-14, all communication between equipment on each side of the link is lost. It would be very inconvenient for a manager to physically reinstate the network immediately and important communication might be lost.

Resilience 4-33

If a spare link could automatically pick up when the broken link failed, the network would appear to function normally to the user. At worst, a few packets would be corrupted or lost.

This is the concept of resilience. One link is on standby (called the standby link) waiting to take over if another link (called the main link) fails, as shown in Figure 4-15. This pair is called a resilient link pair.
