Abstract

Abstract: This paper discusses the lessons learned in the modeling of a software fault tolerance solution built by a consortium of universities and industrial companies for an Esprit project called TIRAN. The requirements of high flexibility and modularity for the software have lead to a modeling approach strongly based on compositionality. Since the interest was for assessing both correctness and performance of the proposed solution, we have cared for these two aspects at the same time, and, by means of an example, we show how this was a central aspect of our analysis.
