Aspects of availability

In this paper, we propose a domain-specific aspect language to prevent the denials of service caused by resource management. Our aspects specify availability policies by enforcing time limits in the allocation of resources. In our language, aspects can be seen as formal timed properties on execution traces. Programs and aspects are specified as timed automata and the weaving process as an automata product. The benefit of this formal approach is two-fold: the user keeps the semantic impact of weaving under control and (s)he can use a model-checker to optimize the woven program and verify availability properties.
