Validation and evaluation of a software solution for fault tolerant distributed synchronization
Paolo Ballarini, Simona Bernardi, Susanna Donatelli · 2003
This paper presents a case study on the combined use of different tools and techniques for the validation and evaluation, from, the early stages of the design, of a fault tolerant software mechanism named distributed synchronization. The mechanism has been specified using UML state charts and sequence diagrams. A number of stochastic well-formed nets (SWN) models have been derived from the specifications: they have been composed using the tool algebra, and the resulting model has been model-checked using the PROD tool for temporal logic properties, thanks to a GreatSPN-to-PROD translator. The quantitative analysis has been performed using the SWN solvers of the Great-SPN tool.
