Handling the Dynamic Reconfiguration of Software Architectures Using Aspects

Currently, most software systems have a dynamic nature and need to evolve at run-time. For this reason, the dynamic reconfiguration of software architectures is a challenge that must be dealt with to enable the creation and destruction of component instances and their links at run-time. This challenge is even greater when there are autonomous composite components which also need reconfiguration capabilities to evolve their internal compositions. This paper presents a novel approach to dynamically reconfigure software architectures taking advantage of aspect-oriented techniques. The approach presented is a platform-independent alternative whose aim is to increase the reuse and to decrease the maintenance effort. It deals with the challenge of reconfiguring composite components that: (1) are easy to maintain, since the dynamic reconfiguration concern is separated from the other concerns; (2) can autonomously reconfigure themselves, since each composite component is provided with dynamic reconfiguration services to change its internal architecture.
