摘要
快速发展的移动代理和网格技术给工作流提供了新的集成各种分布式资源的计算环境。传统的工作流架构有很多弱点,比如在动态环境中缺少灵活性等。提出了一个集成WebServices,网格,工作流和移动代理技术的分布式工作流架构,可以通过移动代理间的通讯来达到工作流之间协同工作,而且这个架构增强了工作流的灵活性和可靠性。以这个新的模型为基础实现了一个具体的工作流工作站,且可实现系统的安全使用。
The developing mobile agent and grid technologies provide workflow with a computing environment by means of integrating various distributed resources. The traditional architecture for workflow has many weaknesses, such as architecture lacks greatly agility in a dynamic environment. A distributed workflow architecture is proposed, which integrates concepts and technologies fi＇om web services, grid, workflow and mobile agent. With this approach, coordination ofworkflow are achieved by communication between mobile agents. Moreover, this approach enhances flexible and reliability. Finally, the workstation ofworkflow based on this prototype is implemented, and the system becomes more secure.
