Edita Djambazova, Rumen Andreev · Problems of Engineering Cybernetics and Robotics · 2023
Dependable distributed real-time systems are usually deployed in safety-critical applications.One of the major requirements for their operation is to be fault-tolerant.Fault tolerance is achieved by using various techniques, most of which are based on redundancy.Traditionally, redundancy in dependable distributed real-time systems is applied at a component level and in communication but it could take many forms.The presented survey investigates the methods and techniques to realize redundancy in dependable distributed realtime systems and attempts to systemize the variety of approaches to implement it.Although redundancy is a well-studied fault-tolerance method, it deserves attention in order to broaden the view on its application and seek opportunities for optimized solutions.
