Implementing the Dependable Operating System Architecture on the IA-32 Architecture

This paper describes the design and implementation of the dependable operating system architecture on the IA-32 architecture. The dependable operating system architecture is composed of Linux and the system monitoring and control system (SMCS), and SMCS executes the monitoring and control services to watch the status of Linux and automatically rejuvenates it when necessary and appropriate in order to improve the dependability of the system. The implementation on IA-32 is designed for the purpose of easier trial and evaluation. It takes advantage of Linux on IA-32, which provides more features. The design enables the dependable operating system architecture to be installed with a very small amount of effort on systems with a variety of Linux distributions.
