Abstract EN:

This thesis presents a novel active architecture for building and deploying network services: ASWA, Web Services based Active network Architecture. At the architectural level, ASWA defines an active node whose functionalities are divided into the Node Operating System, the Execution Environment, and the Active Applications. At the implementation level, ASWA is a Web Services based platform where new components can be added and deployed, in order to dynamically modify network nodes behavior. Applications can be developed with any language and communicate across heterogeneous environments, and across Internet and Intranet structures. At the deployment level ASWA uses an active node approach, and offers a controlled deployment mode. In terms of security, Authentication of deployed code and protection of the nodes is achieved by the use of HTTPS and the header extensions of the SOAP envelope. This thesis proposes a new Active Policy-based Network Management architecture which defines, deploys and integrates a policy-based management protocol, in conformity to the COPS protocol, into the active ASWA framework. This thesis also proposes a new approach for the definition of network policy management information, in order to enhance its semantic expressiveness and facilitate its maintenance, by using OWL the Web Ontology Language and its extension SWRL. The combination of the 4 paradigms: PBN, Active Networks, Web services and Semantic representation of information proves to be a promising integrated and portable solution for representing active nodes, conceiving and deploying active services, and more specifically intelligent management services.
