基于Agent的网构软件构件模型及其实现

网构软件代表了Internet环境下的一种新型的软件形态,但仍然面临着外部环境显式化、软件实体主体化、运行机制自适应等问题.从构件的角度出发,提出了EBDI(electronic business document exchange)结构以表示能够根据环境变化实施自主行为的构件,利用动态绑定关系解释了构件的自适应演化特征.根据形式化的Role模型,描述了构件的运行状态、自主运行及自适应演化运行机制.开发了DAgent-Internetware原型作为网构软件的支撑平台,支持以DAgent为构件的网构软件从设计到实现、部署、运行、演化等一系列流程.

Component Model and Its Implementation of Internetware Based on Agent

As a novel software paradigm evolved by the Internet, Internetware is still faced with many challenges, such as expressing explicit environments, autonomous software entities, self-adaptive run mechanisms, etc. From component perspective, this paper presents EBDI (electronic business document exchange) architecture to describe the components which can autonomously plan themselves at runtime to handle variable environments, and uses dynamic binding relationship to illuminate the self-adaptive and evolutionary components. Throughout formal role model, run status, autonomous run and dynamic evolving run mechanisms for components of Internetware are addressed. As the platform of Internetware, DAgent-Internetware prototype can provide support for Internetware based on DAgent to design, develop, deploy, run and evolve.
