Software redundancy fault tolerance
WebJan 1, 2013 · Hardware redundancy impacts the size, weight, power consumption, and cost of a system. In some applications, it is preferable to use extra time rather than extra hardware to tolerate faults. In this chapter, we describe time redundancy techniques for detection and correction of transient faults. We also show how time redundancy can be … WebJun 24, 2024 · Redundancy can be understood as two servers with duplicate or mirrored data.

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.
