Abstract:
Composite service evolution is one of the most important challenges faced in the field of service composition. And how to migrate running instances to the evolved definition is a critical issue for correct service evolution. In this paper, we proposed a hybrid instance migration approach in the aim of both increasing migration efficiency and flexibility. Based on Single Entry Single Exit fragments and process structure tre, we reduce the change region calculation algorithm’s time complexity from exponential time to linear time. Moreover, our instance migration approach also includes data dependence analysis to avoid data flow problems during migration. This makes our approach more practical since data flow correctness preservation is critical in real world application. Finally, prototype system is given and experiments are carried out to prove the feasibility of our approach.
