Abstract
In an increasing number of domains software is now required to be self-adapting and self-healing. While in the past such abilities were incorporated into software on a per system basis, proliferation of such systems calls for more generalized mechanisms to manage dynamic adaptation. General mechanisms have the advantage that they can be reused in numerous systems, analyzed separately from the system being adapted, and easily changed to incorporate new adaptations. Moreover, they provide a natural home for encoding the expertise of system designers and implementers about adaptation strategies and policies. In this paper, we show how architecture description languages and tools can be extended to provide such generalized dynamic adaptation mechanisms.
