Résumé

Cet article présente la mise en œuvre et les résultats d’expérimentation d’une plate-forme de validation basée sur des méthodes formelles. Cette plate-forme permet de réaliser des tests de conformité et d’interopérabilité, d’analyser la QdS (Qualité de Service) et de produire un modèle de performance pour les services. Elle couvre toutes les étapes de validation: spécification formelle, définition des architectures de test, génération et exécution des tests sur une architecture donnée, et l’évaluation des performances. Les méthodes de test et les architectures présentées facilitent la détection et la localisation des erreurs.

La plate-forme a été réalisée dans le cadre d’un projet plate-forme duRnrt (Réseau National de Recherche en Télécommunications),Platonis. Cette plate-forme possède une configuration réseau au niveau national avec des sites dans les laboratoires partenaires du projet.

Les systèmes de télécommunications et la téléphonie mobile sont les domaines principaux d’application de la plate-forme. En particulier, deux études de cas sont présentées, celles-ci illustrent son application au test des protocoles et des services pour les réseaux cellulaires de 3e génération (utilisant leWap, gprs etUts). Mais il s’agit d’une plateforme générique qui pourra être utilisée pour d’autres types de services et protocoles de communication.

Abstract

This article presents the implementation of a validation platform based on formal methods and the experimental results obtained. This platform allows performing conformance and interoperability tests, analysing the specification and constructing a performance model for the services. It covers all stages of the validation which are: formal specification, test architecture definition, test generation and execution for the defined architecture, and performance evaluation. The test methods and architectures used here make it easier to detect and localise errors. The platform has been constructed within the framework of theRnrt (National Telecommunications Research Network) platform project, platonis. This platform is composed of a network integrating the different sites of the project partners. The principal application domains for the platform are telecommunication systems and mobile telephony. In particular, two different cases study are presented that illustrate the platform’s applicability to the test of mobile 3rd generation protocols and services usingWap, gprs andUmts. Nevertheless, the platform is generic and can be used for other types of communication protocols and services.
