方面化中间件平台全息视图语言——HVL4DCAM


  摘 要:为满足方面化双核中间件平台DCAM面向按需计算的自适应需求,并支持系统平台的实时重构为目的的中间件计算环境,通过分析现有面向方面体系结构描述语言,提出了一种基于XML的中间件平台全息视图语言——HVL4DCAM。HVL4DCAM可以实时解析运行于平台之上的构件和方面的状态以及它们之间的动态关系,实现了构件和方面的对称性描述,提升方面的可重用性。基于HVL4DCAM描述了运行于DCAM之上的绩效考核系统中的构件及方面的关系,以及它们与DCAM平台的关系,并给出了进一步研究的内容。

  Abstract:To satisfy the self-adaptation requirement of on-demand computing of aspectual dual core middleware platform DCAM, which was a middleware computing environment, and supported the real-time reconstruction of system platform, proposed a kind of holographic view language HVL4DCAM for middleware platform based on the analysis of the existing aspect-oriented architecture description languages. HVL4DCAM could analyze the real-time states of components and aspects which were running on platform and the dynamic relationship between them. HVL4DCAM realized symmetrical description of the components and aspects, and improved aspects reusability. Based on HVL4DCAM, presented the description of the relationship between components and aspects of a performance assessment system that was running on DCAM and the relationship between components and DCAM as well. Finally this paper presented the further research work.
