Fault tolerant and its techniques

There are different types of fault tolerant which include software and hardware fault tolerant techniques. This paper surveys different techniques and methodologies of software fault tolerance. These techniques include traditional and new techniques. Traditional techniques consist of n-copy programming, n-version programming, retry blocks (RtB), n-self-checking Programming and new techniques are fuzzy voting, abstraction, parallel graph reduction, rejuvenation and adaptive n-version systems
