基于移动agent的软件实体适配技术研究

在开放的Internet平台上，通过对已有软件实体进行集成以构建应用系统成为一种重要的软件开发方法．其中软件适配技术是关键技术之一．传统适配技术对Internet这个开放平台上的软件集成的支持存在欠缺，主要表现在对可组合、可重用、可配置和可移动的支持不够．利用agent的移动性和封装能力，提出了一种基于移动agent技术的适配方法．提出了一个统一的agent集成框架及其支撑技术，有效支持软件适配内容的封装和运行．在该框架中，对适配的一个重要方面——组合实体——进行了探讨．最后介绍了移动agent适配技术的系统实现．

Mobile Agent-based Adaptation Technology of Software Entity

Constructing software applications by integrating existing software entities is becoming an important method for software development in the open Internet platform,where adaptation technique for software entities is regarded as one of the key techniques.Traditional adaptation approaches exhibit some deficiencies for software integration in this open platform,including relatively weak support for software combination,reusing,configuration and mobility.An agent-based technique is proposed in this paper,utilizing mobility and encapsulation of mobile agents.Firstly,a uniform agent-based framework for software integration is introduced with its supporting mechanisms,which supports effectively encapsulation and execution of adaptation codes.Two issues are discussed in this framework: one is the adaptors with mobile agents,i.e.mobile agents encapsulate the adaptation codes and are dispatched to the site where the target software entity hosts,and accomplish the adaptation by intercepting and processing invocations;the other is the construction of composite entity and two fundamental structures realized by mobile agents are introduced in this paper.Secondly,the design and implementation of this agent-based adaptation technique are provided.
