|Title:||Engineering Self-Managed Adaptive Networks|
Daphné TUNCER is currently a Research Associate in the Communications and Information Systems Group (CISG) at the Department of Electronic and Electrical Engineering, University College London (UCL), UK. She obtained her Ph.D. in Electronic and Electrical Engineering from UCL in November 2013. Before joining UCL, she received a "Diplôme d’ingénieur de Télécom SudParis" (equivalent of a Master’s Degree in ICT Engineering) from Télécom SudParis, FRANCE, in 2009. Her research interests are in the areas of autonomic communication, network self-management and more generally in decentralized approaches to support adaptive network resource management.
PhD project description
In order to meet the requirements of emerging services, the future Internet will need to be flexible, reactive and adaptive with respect to arising network conditions. Network management functionality is essential in providing dynamic reactiveness and adaptability but current management approaches have limitations which prevent them from meeting these requirements.In search for a paradigm shift, recent research efforts have been focusing on autonomic/self-management principles, whereby network elements can adapt themselves to contextual changes without any external intervention through adaptive and flexible functionality.
This thesis investigates how autonomic principles can be extended and applied to fixed networks for quality of service and performance management. It presents a novel resource management framework which enables intelligence to be introduced within the network in order to support self-management functionality in a coordinated and controllable manner. The proposed framework relies on a distributed infrastructure, called the management substrate, which is a logical structure formed by the ingress nodes of the network. The role of the substrate is illustrated on realistic resource management application scenarios for the emerging self-managed Internet. These cover solutions for dynamic traffic engineering (load balancing across multiple paths), energy efficiency and cache management in Internet Service Providers.
The thesis addresses important research challenges associated with the proposed framework, such as the design of specific organisational, communication and coordination models required to support the different management control loops. Furthermore, it develops, for each application scenario, specific mechanisms to realise the relevant resource management functionality. It also considers issues related to the coexistence of multiple control loops and investigates an approach by which their interactions can be managed. In order to demonstrate the benefits of the proposed resource management solution, an extensive performance evaluation of the different mechanisms described in this thesis have been performed based on realistic traffic traces and network topologies.
