Towards Resource-Aware Runtime Reconfigurable Component-Based Systems

The overall Quality of Service (QoS) delivered by a system depends on the resources available to its constituting components. Achieving predictable QoS behaviour therefore requires a resource-aware component framework. Moreover, for applications that exhibit highly fluctuating loads and that have to compete for resources at runtime, the framework must also allow dynamic reconfiguration. The goal of this paper is to explore some basic principles and architectural choices for building such a resource-aware component framework that allow predictable composition of a system from distributed components. Major features of the envisioned framework are: wrapping components into networked services, automated extension of those services with resource management, and runtime third-party composition of the networked services.
