网格环境中基于移动Agent的工作流架构研究

Research Of Workflow Frame for Mobile Agent-Based In Grid Environment

传统的工作流架构有很多弱点,比如架构严重降低了系统性能,在动态环境中缺少灵活性。本文提出了一个集成了WebServices,网格,工作流和移动代理技术的分布式工作流架构。在这个架构中,我们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。最后,以这个新的模型为基础实现了一个具体的工作流工作站。

The traditional architecture for workflow has many weaknesses, such as architecture seriously degrades system performance, and lacks greatly agility in a dynamic environment. In this paper, we propose a distributed workflow architecture, which integrates concepts and technologies from web services, grid, workflow and mobile agent. With this approach, coordination of workflow is achieved by communication between mobile agents. Moreover, this approach enhances flexible and reliability. Finally, we implements the workstation of workflow based on this prototype.
