Abstract

Over the past decade researchers have shown that software architecture provides an appropriate level of granularity for assessing a system's Quality of Service (QoS) properties (e.g., latency). Similarly, many previous works have adopted an architecture-centric approach to reason about the runtime adaptation, including component mobility, of software systems. However, the relationship between software architecture, QoS, and mobility is not clearly understood. In this paper, we present a framework that takes an explicit software architecture perspective for assessing the system's QoS properties, and improving it through architectural mobility. We describe the implementation of the framework, as well as some of the remaining challenges that frame our ongoing work.
