Abstract:We examine deadlock analysis for service-oriented systems with unbound concurrency and unbound recursion. In particular, abstraction-based approaches are considered, i.e., abstract behavior models are derived from service implementations and composed according to the architecture of service-oriented systems. It turns out that there are some limitations of Petri-net-based approaches, e.g., such as workflow nets if deadlocks are analyzed. We show an example that ends in a deadlock if recursion is considered but … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
