摘要
移动Agent被普遍认为是一种有潜力的网络分布式计算技术,但至今仍没得到广泛的应用,主要是因为移动A-gent中尚存在一些主要问题,如环境灵活性、通信、代码迁移、安全等。针对这些问题,提出了一种基于Jini技术的移动Agent模型。通过将Jini中的查找、发现、租约、远程事件、对象存储等概念和服务加入到移动Agent中,创建了一个包含两种网络中间件(代理基站和代理站点)的动态分布式移动Agent模型,该模型提供了一种新的查找、通信、安全和容错方案以提高移动代理的健壮性、安全性和代理间的交互性。同时对该模型中关键技术的实现机制作了分析。
The mobile agent is widely considered as a promising network distributed computing paradigm,however,so far it has not been fully applied for it's some limitations such as environment flexibility,communication,code migration,security etc.For these problems ,a Jini-based mobile agent model is proposed.By adding some concepts and services of Jini such as lookup,discovery,remote event and lease into mobile agent ,a dynamic distributed mobile agent model con-sisting of two network middlewares(AgentBase and AgentStation)is constructed.The model provides a new communica-tion,collaboration,security and fault tolerance approach to improve the mobile agent's robustness,security and inter-op-eration between agents.At the same time ,the implementation of critical technology in the model is analyzed.
