Abstract

In the paper a comparison of processing time and reliability performance for the Recovery Blocks scheme and N-Version Programming technique is presented. Derived queueing models can be useful in deciding which of the strategies should be used, depending on system parameters.

Keywords: Software fault tolerance, modeling, performance evaluation, reliability evaluation
