QoS-Aware and Ontology-Driven Autonomic Service Bus

Distributed applications and more generally distributed systems are increasingly based on services that are integrated to implement complex functional processes. Diversity and heterogeneity of these services raise many needs for the integration. To meet these needs, the Enterprise Service Bus has been proposed for the development of standard based collaborative strategies between services and applications. However the lack of semantic, the competitiveness between services and the dynamicity of service-oriented architectures contexts (mobility, increase of consumers and providers of services, etc.) are the reason of unpredictable events such as service unavailability, high overhead and response time, decrease of reliability, security, etc. Those events ask to adapt the established integration strategies to ensure or improve performance and Quality of Service offered by the Enterprise Service Bus. In this context, we propose a QoS-aware and ontology-driven Autonomic Service Bus able to take into account non functional properties' semantics in order to offer self-configuration and self-adaptation functionalities. Beyond the traditional objectives of enterprise service buses, our proposal includes the use of well known transport and network mechanisms to take into account autonomously both functional and non functional properties asked or offered by services consumers or providers.
