面向Aspect的操作系统研究

面向Aspect软件设计是一种新的软件设计思想和技术.分析了近年来操作系统贯穿特性与Aspect概念,构件重构、系统演化与设计,系统安全、性能检测与容错这3个方面的研究成果,指出面向Aspect操作系统研究已经获得了积极的成果.但是,目前的研究缺乏一定的深度和广度,尚没有在操作系统的设计阶段运用AOP(Aspect-Oriented operating)思想的成果出现.在已有操作系统代码中抽象Aspect的过程中,缺乏完整的工程化和规范化的研究.这些问题的解决有赖于面向Aspect研究的进一步深入.最后,对面向Aspect操作系统研究的前景进行展望,认为有关AOSD(Aspect-Oriented software development)的研究有可能对未来操作系统的发展产生重大影响.

Research on Aspect Oriented Operating Systems

Aspect-Oriented software development (AOSD) is a new type of software design idea and technique. This paper analyzes recent research results in three fields which are: (1) the crosscutting concerns and Aspect concept in operating systems; (2) component reconstruction, system evolution and design, and system security; (3) performance monitoring and fault tolerance. The paper points out that some positive research results of Aspect-Oriented operating systems have been acquired. However, the current research results lack necessary deepness and extent, the operating systems that adopt the Aspect idea during design stage do not exist yet, and there is no whole engineering and standardization for Aspect extraction procedure in the existing operating systems code. The solutions for these problems rely on further Aspect-Oriented research results. Final, the paper describes the respective of Aspect oriented operating systems research and indicates that the research of AOSD may possibly bring a significant impact to the research and development of future operating systems.
