SwinDeW-S: extending P2P workflow systems for adaptive composite Web services

摘要

SwinDeW, an innovative decentralised workflow management system, has established an underlying framework for peer-to-peer (p2p) based business process coordination environments. SwinDeW-S extends SwinDeW to support adaptive composite service orchestration in the era of service-oriented computing. This paper comprehensively presents features of SwinDeW-S, including the p2p network establishment, the messaging mechanism, the service deployment and enactment, the service discovery and advertisement, and the service flow execution. The prototypical extension of SwinDeW to SwinDeW-S and the advantages of SwinDeW-S are also examined and analysed. With the innovative integration of service and p2p-based enterprise application techniques, SwinDeW-S can support composite service orchestration, deployment and execution.
