Abstract

A method for achieving fault-tolerance in distributed systems is proposed and compared with the known method of error masking based on distributed voting over the results of several variants. The method is called error attenuation, since the errors produced by nonpermanent faults attenuate eventually during the further execution of the variants. The term attenuation is used to represent the fact that error masking is obtained not in one step, but gradually, in several steps. The proposed method for error attenuation is studied for systems with distributed majority voting and with distributed plurality voting, and for systems implementing adaptive strategy
