Graceful Interruption of Request-Response Service Interactions

摘要

Bi-directional request-response interaction is a standard communication pattern in Service Oriented Computing (SOC). Such a pattern should be interrupted in case of faults. In the literature, different approaches have been considered: WS-BPEL discards the response, while Jolie waits for it in order to allow the fault handler to appropriately close the conversation with the remote service. We investigate an intermediate approach in which it is not necessary for the fault handler to wait for the response, but it is still possible on response arrival to gracefully close the conversation with the remote service.
