WebHow much redundancy does a system need to achieve a given level of fault tolerance? A system is said to be k-fault tolerant if it can withstand k faults. If the components fail silently, then it is sufficient to have k+1 components to achieve k fault tolerance: k components can fail and one will still be working. If the components exhibit ... As in the case of hardware, the goal of fault detection in software is to determine if a fault has occurred within a system. Single-version fault tolerance techniques usually use various types of acceptance tests to detect faults. The result of a program is subjected to a test. If the result passes the test, the program … See more Fault containment in software can be achieved by modifying the structure of the system and by imposing a set of restrictions defining which actions are permissible within the … See more A program is represented by the flowgraph shown in Fig. 7.2. The worst-case execution time of each block is shown inside the block. … See more Once a fault is detected and contained, a system attempts to recover from the faulty state and regain operational status. If fault detection and containment mechanisms are implemented … See more Suppose that a program code contains an expression of a Boolean function, e.g. Then, a data-diverse version of this code may contain a functionally equivalent, but different expression … See more
