基于Mobile Agent技术的遗留系统再工程方法

针对因特网环境下遗留系统需要不断引入新的需求和技术的需要,提出了一种基于Mobile Agent的遗留系统再工程方法.在该方法中,对遗留系统采用Agent思想重新建模,将频繁的需要与其他部分交互的组件实现为移动Agent,并且允许以定制的Agent的方式添加新的需求,使得目标系统能够更加适应因特网环境.通过将一个单机环境下的单用户计算软件迁移到网络环境下,允许多个远程用户并发访问的再工程尝试,为遗留系统引入新的需求和技术提供了一条可以选择的途径.

A Solution to Reengineering the Legacy System Based on Mobile Agent Technology

In this paper, a solution to reengineering the legacy system based on mobile agent technology is proposed to satisfy the demand of continuous introducing new requirements and techniques into legacy system. An agent viewpoint is adopted to model the legacy system, with the components frequently interacting with others implemented as mobile agent and new requirements added as customized agents. Through the practice of migrating a standalone single-user computing software onto networking platform with the support of several remote user's concurrent accesses, an alternative way of introducing new requirements and technologies into legacy system is proposed.
