Explanation:
Watchdog timers are commonly used to detect software fault, such as aprocess ending abnormally or hanging.

This guards against software deadlocks, infinite loops, and processprioritization problems. This functionality can be used in AAA protocols to know ifpackets need to be resent and if connections that are experiencing problems need tobe closed and reopened.
