摘　　要：随着Internet上提供在线复用的构件增多,用这种构件服务组装软件系统就成为可能.本文首先针对Internet环境构件组装系统分析了现有相关技术的不足,讨论了组装技术应用上的关键问题.为此将构件与传统的数据流计算模型相结合,设计并实现了支持广域构件组装的DFCM组装框架;给出了DFCM的总体结构,描述了其中的关键技术;经过对原型系统的模拟表明该模型框架是有效的,能够充分利用Internet固有的并行性,具有扩展性.With the widespread of component services over Internet, it is possible to composite software system with the service. The component composition problems for Internet plate are discussed and the present Web services composite technologies are investigated in this paper. To solve this, DFCM framework is designed and implemented, which supports execution and management of composite components over Internet by integrating traditional dataflow computing model with components. DFCM architecture is described and some key technologies are presented. Simulations of the prototype system shows that is reasonable and effective in that it has high scalability and parallelism for the resources of components over Internet.
