A Component-based Framework for the Specification, Verification and Validation of Open Distributed Systems

Abstract

Open distributed systems have inherent complexity related to their control that makes it necessary to have a component-based approach to each of the activities undertaken along their life-cycle. Such an approach allows to apply the divide and conquer principles. In this paper, we propose a framework to undertake the specification, the verification and the validation (V&V) of distributed systems based on those composition principles. The approach herein uses a specification model which allows to describe the components of a distributed system. This model focuses also on the description of the interactions between the components in order to compose them into (sub- )systems. The properties expected are described and verified in a compositional way from the components to the (sub-)systems. The specification model is automatically transformed into a V&V model which is a modular Petri net standing with an object-based semantics. The verification of the properties is performed by model-checki..
