Résumé : 

Reduce the time to market, cost and improving the quality are major issues for a company to gain users and race the competitors. Telecom Service (TS) Specification is an important activity, as it represents the TS properties and prepares its design to be implemented.

The aim of this ongoing thesis is to provide the different stakeholders that are involved in the TS specification activity with tools and methods that assist during this activity, in order to face the competition. Detecting errors and flaws in the TS design helps in that purpose, as such errors may result in expensive consequences from the implementation to the rest of the TS development activities. Thus, relying on Model Driven Engineering and Model Driven Analysis approaches, we propose to verify the TS design earlier than the implementation activity.

In order to link between the two activities (design, and early verification), we propose the abstract syntax of Domain Specific Early Verification Modeling Language (DSEVML) that relies on ArchiMate (a set of languages for EA framework) and extends a recently defined design language [1]. The proposed language contains necessary elements to implement and verify the TS design using different types of well known tools. Network simulators provide the TS designer means to obtain measurements from the models of TS design, so we have chosen network simulators as tools for early verification activity. The proposed Meta-Model (abstract syntax) reflects a transversal alignment between measurements and ArchiMate 3 layers (Business, Application, and Technology). Eclipse provides us with the useful modeling tools (EMF) to do our work. Thus, using EMF we have implemented a tool selection method to identify the proper network simulator due to its measurement capabilities. This identifies a list of tools and enables the usage of code generation template to link the design models directly to the simulators which we have implemented too. Our approach: (i) makes it possible to classify tools and their collected data due to their domains thanks to the different viewpoints of Telecom System (business, application, technology); (ii) expected to reduce the time to implementation thanks to the code generation of a TS models for network simulators.
