An Execution Mechanism for Composited Service Based on Prioritized Message Passing

Service composition which composes available services to new value-added services is an important application constructing pattern. Current execution mechanisms cannot effectively execute complex composition process with many concurrencies. A prioritized message passing based execution mechanism is put forward. First introduces the research background of a new business service based domain oriented composite service model, and then the key aspects of message life cycle, execution process and priority structure are proposed. In the end a reference framework of implementation is presented.
