Une Ingénierie d'Architecture pour une évolution trans-génération aux NGNs : Intégrations verticale et horizontale

Abstract : The network domain, in the heart of the information and communication technologies, has been distinguished, the last few years, by the growth the users demand, coupled with a multidimensional evolution of the value-added offers, and the end users requirements. In order to fulfill these requirements, the solutions proposed today deal with the issues that occur on a specific architectural level without considering the whole architecture. Indeed, the solution related to the transport level deals with the evolution of the infrastructure of the connectivity platforms (UMTS, xDSL, IP/MPLS, etc.) and the related QoS issues (such as: network resource reservation). The same analysis is applicable to the solutions dealing with the applicative services level that develop and deploy new service platforms (IN, OSA, Application Servers, etc.) and the related QoS issues (such as: applicative resource reservation). The objective of this thesis is to propose a global vue and solution by introducing a global integration concept of the telecommunication architectures, including all actor of the end-to-end overlay levels: network elements; network, applications/services and end-users. We call this concept Architecture Engineering. It is based on: (i) a cohabitation model between the different layers in order to guarantee the consistence of the whole architecture, i.e. the superposition of the architectural modules should be complementary and non redundant for an end-to-end QoS fulfillment. (ii) a cooperation model in order to monitor and evaluation in a real time way the QoS provided by the different networks composing the level. The objective is the automation of the process of deployment of new services while ensuring the required QoS. For the cooperation model in the Network level we propose a Self-organization algorithm of the network elements in order to maintain the horizontal QoS. We call this algorithm: Path-Based Clustering. In order to proof the Architecture Engineering and the related models (Cohabitation and Cooperation) concept, we designed a platform called Organizational Pilot (POrg) considering three (3) dimensions: Organizational, Functional, and Architectural. (i) The organizational dimension defines the role, scope and location of each component of POrg platform. We implemented POrg as a multi-agent platform integrated in each equipment and can be activated at any time if needed. They are in charge of declination of the QoS requirements and reorganization of the domains. (ii) Functional dimension that defines all functions and actions performed by POrg in order to maintain the QoS in an automated way. The implementation of this dimension is done using UML. All functions and actions are modeled using UML Use Cases. (iii) The Architectural dimension that defined the structure and the coordination between POrg modules. For a coherence and genericity goals, we divided POrg into two (2) parts : the first part allow POrg to communicate with its environment. The second part is the Kernel, that includes all internal processing related to the agent. The separation between processing and communication allows POrg to be integrated to any element, ensuring thus, the evolutivity and adaptability required for POrg. The implementation of POrg proofs the feasibility and the relevance of our solution.
