Under the DynRIIC project, we produced results in two primary areas of QoS management for information spaces: architecture and algorithms. In the architecture area, we conceived, designed, and prototyped a multi-layered QoS management architecture suitable for information spaces. The multi-layered QoS management system works alongside the information manager in an information space and assigns QoS levels and resource allocations, produces and enforces QoS policies, and actuates QoS controls, including resource controls and information shaping. In the algorithms area, we developed several QoS allocation algorithms that work with the QoS management system, including resource and QoS allocation for single and multiple information spaces. We evaluated the algorithms indicating the relative merits and use of these algorithms in various scenarios, and prototyped some of the algorithms in the QoS decision maker components of the QoS management system.
