On the role of software architectures in runtime system reconfiguration

Society's increasing dependence on software-intensive systems is driving the need for dependable, robust, continuously available systems. Runtime system reconfiguration is one aspect of achieving continuous availability. We present an architecture-based approach to runtime software reconfiguration, highlighting the role of architectural styles and software connectors in facilitating runtime change. Finally, we describe the implementation of our tool suite, called ArchStudio, that supports runtime reconfiguration using our architecture-based approach.
