Tandem System

Classification Key : Exterior Security, Tampering


Failure in one component often starts the domino-effect and the failure is propagated to bring about the entire system failure. How can the system be made tolerant to this fault?


Structure a system so that an independent failure of one component will be detected quickly and so that an independent single-component failure will not cause system failure. Use multiple components to perform the tasks and report the result only if the result is similar for both the components.

Known Uses
