摘要
移动 Agent技术广泛应用于移动计算或分布计算领域。文中对现有五种典型的移动 Agent系统在语言、迁移机制、通信机制和安全性等方面做了比较 ,并在 IBM的商用移动 Agent平台 Aglet上实现了基于移动 Agent的分布数据库访问 :移动 Agent被派遣到远程数据库服务器 ,进行数据库访问 ,并把结果带回来。现有移动 Agent平台在可管理性、安全性、自主性方面仍存在问题 。
Mobile Agent technology has been widely used in mobile computing and distributed computing. This paper presents a comparison of five existing mobile agent systems in the aspects of languages, migration mechanisms, communication and security. Then several demonstration programs have been implemented on IBM Aglet--a commercial system where Aglets can migrate to remote database servers, access databases and bring the information back. There are still difficult problems such as manageability, security and autonomous, which need to be solved for practical applications.
