摘要

Autonomic systems undergo dynamic compositional adaptation that often require state transfer and synchronization to correctly initialize the state of the new component, while ensuring that multiple fractions of the component are added and removed consistently. In general, if there are n different components for a given functionality, then there exist n(n - 1) possible adaptations for selecting an appropriate component. Identifying all these adaptations is not an easy task. Moreover, as verification of such adaptations is also difflcult, it is desirable to reduce total number of these adaptations.We propose a component family design for systematically building a repository of components from the perspective of dynamic adaptation. For a family of n components, we show that it suffices to identify n different adaptations. Moreover, to add a new component to this family, it suffices to consider only two adaptations. We also propose a design to separatethe adaptation concern from component functionality for simplifying the specification and verification of adaptation. We introduce the enhanced-primitive relation between two components; when such a relation is known to exist, we show that it is possible to simplify the adaptation and its verification.
