| 摘 要： | 针对由BPEL4WS描述的面向过程的组合服务,详细分析了组合服务的执行过程,提出了基于移动Agent的组合服务执行机制。这种P2P的组合服务执行方式,能够克服集中式的缺陷,有效降低网络负载。由于Agent迁移本身的消耗,本文研究并设计了移动Agent的驻留策略,能有效避免移动Agent不必要的重复迁移,大大提高了执行效率,进一步降低了资源消耗。

| Abstract: | This paper proposes a mobile agent based composite service execution mechanism to achieve the process oriented composite service represented by BPEL4WS. This paper also gives a detailed process of execution of composite service. Mobile agent based composite service execution is a P2P （peer-to-peer） execution model which can avoid the performance bottleneck of center peer and effec- tively reduce the network load. Due to the cost of agent migration, this paper investigates and designs a mobile agent resident strategy to avoid unnecessary migration, which raises execution efficiency greatly and reduces the resource consumption. |
