Policy-based management has been proposed in recent years as a suitable means for managing Quality of Service (QoS) in IP networks. Yet despite research projects, standardisation efforts, and substantial interest from industry, policy-based management is still not a reality. One of the reasons for the reticence to adopt this technology is that it is difficult to analyse policies to determine that they will actually work, given the capabilities of managed network devices, and to guarantee the stability of the network configuration, given that policies may have conflicts leading to unpredictable effects. This project aims to address the challenges of policy analysis, policy validation and policy refinement within the specific application domain of Quality of Service for IP networks. …

Future e-science and e health applications will involve mobile users, possibly with on-body sensors interacting with a ubiquitous computing environment which detects their activity, current context and adapts accordingly. However, the promise of such ubiquitous computing environments will not be realised unless these systems can effectively disappear and for this they need to become autonomous by managingtheir own evolution and configuration changes without explicit user or administrator action. This project will develop the architecture, tools and techniques which permit these environments to become self-managing. To provide self-managment at varying levels (for individual devices, for simple body-areaor home-area networks, as well as large scale network infrastructures) we advocate the concept of a self managed cell (SMC) as the basic architecture pattern at both local and intergrated levels. We will define, prototype and evaluate architectures based on the SMC pattern and their use in e-health applications. To this end we will: define and implement the core SMC pattern in terms of the monitoring, service-discovery, context and policy-control services required for basic adaptation mechanisms, investigate how SMC’s can be dynamically structured into large structures and specialise SMC’s and their interactions for two e-health application scenarios.
