Abstract
Transaction commit protocols have widely been used to ensure the correctness and reliability of distributed applications. This paper investigates into the performance of such protocols within the context of composite Web services. It presents a new commit protocol which aims to improve the performance of composite Web services transactions. The proposed protocol is tested through various analytical experiments. These experiments reveal that the proposed protocol significantly improves the performance in committing a composite Web service transaction. The experiments also exhibit the processing overhead of the proposed protocol in the case of unsuccessful execution of a Web service transaction
