主体命名方式AST

AST-A METHOD OF AGENT NAMING AND LOCALIZATION

主体的命名和定位是移动主体中的关键技术 ,它的优劣影响到整个移动主体系统的性能 .在分析了目前几种主体命名和定位方式之后 ,提出一种新的主体命名和定位的方法 :Agent Shadow Tracing.这种方法将主体看成是生成它的主机的一种资源 ,为主体在生成它的主机上分配一个固定的界面 (shadow) ,在主体移动时 ,别的主体和程序可以通过与界面交互达到与移动主体通信的目的 .这种方法避免了目前主体命名和定位方式的一些缺点 ,较好地解决了移动主体之间的通信问题 .

Agent naming and localization is the key technology in mobile agent. How it is implemented affects the performance of the whole agent system deeply. A new method named agent shadow tracing is proposed to implement the agent naming and localization, after analyzing three approaches in agent naming and localization. This method treats agents as some source of the host that generates it, and assign a shadow to the agent so that other agent and program can communicate with it through the shadow when the agent moves around the network. Also discussed are the security of AST and its advantages comparing with other methods. This method avoids some known disadvantages in the existing methods.
