【摘要】 迁移工作流是解决当前工作流管理领域不完全业务过程定义的一个新的研究方向,通信机制是迁移工作流系统实现的一个关键问题。本文在分析通信需要解决的主要问题的基础上,提出了一种适应迁移工作流系统特征的通信模型,给出了模型框架结构,并详细描述了其中的迁移实例通信算法。模型在实现可靠异步通信的同时,能够保证信件的顺序和 exactly-once 提交,降低寻址时间,减小三角路由的带宽占用,增强系统对规模扩大的适应能力,使算法在通信与迁移都较频繁时仍能保持较高的效率。更多还原

【Abstract】 Migrating workflow is one of recent highlights to solve the problem of incomplete process specification.Just like other mobile-agent-based systems,communication mechanism is still an important aspect in the research of migra- ting workflow systems.In this paper,after analyzing the main problems unsolved in communication of migrating work- flow,a reliable asynchronous communication model and related algorithms are provided which are aimed at the specific organization characteristics of migrating workflow.The algorithms could ensure reliable communication,but also re- duce response time,decrease costs of triangle routing and improve adaptability to the scale enlargement of the migrating system.更多还原
