摘　　要：许多当前的操作系统研究包括设计、实现和分析修改内核,来改进通用的或特定用途的应用性能,但它往往忽视了所要研究的目标,随着其研究的发展,操作系统的大小和复杂度不断地增加,已成为计算机系统中最复杂的软件。正确的研究应该是直接寻找新的方法构造操作系统,为了增加其柔性,允许它根据实际应用作出自适应的改变。研究了当前可扩展操作系统的主要问题,提出了可扩展操作系统的三个关键设计点,并深入分析和论证了每个设计点中各种具体的可扩展技术,为操作系统的进一步研究和开发提供了科学的方法。Many current operating systems research efforts include the design, implementation, and analysis of kernel modifications for improve performance in either generalpurpose or applicationspecific cases.But they usually neglect the research goal,the size and complexity of operating system increase over time. As a result,operating systems become the most complex software in a computer system.Correct operating system research is aimed at finding new ways to construct the operating system in order to increase its flexibility, allowing it to adapt to change in designing such extensible systems and the array of choices facing the operating system designer. We discuss such question for extensible operating systems and then present three key design point for extensible operating systems, we analyze and argue each point that relate to different extensible technology. Provide scientific methodology for operating systems research or development.
