Fault Tolerance in Networks

Fault tolerance in networks refers to the system's ability to continue functioning smoothly despite failures or issues in some parts. Think of it as having backup routes or components that kick in if the main ones break down, ensuring continuous data flow. This is achieved through redundancy, where multiple paths or devices share the workload, and automatic failover mechanisms that detect problems and switch to backup options instantly. Overall, fault tolerance increases reliability, minimizes downtime, and ensures network services stay available even when parts of the system encounter problems.
