An architecture for autonomie management of overlay networks

Recent efforts in service composition has led to an increase in the number of available services on the Internet. As a result, networks became more service centric. The heterogeneity of network components and access technologies made the management of these services more complex and time consuming. In an effort to ease the management of Service Specific Overlay Networks (SSON), we propose a new architecture which exploits the use of overlays to hide the complexities in the network infrastructure while supporting the service specific management. The proposed architecture is designed to integrate autonomie principles in order to facilitate the management of networks with minimal human intervention. It proposes the use of SSON on top of the overlay network to deliver the services users request through a hybrid overlay structure. The proposed architecture also includes a utility-based feedback mechanism to monitor the Quality of Experience (QoE) of services in order to ensure that service providers meet the quality expectations of users. Simulation results indicate a significant improvement in terms of node joining delay and overhead compared to current technique.
