Abstract

With the improvement of the reliability requirements of modern computer systems, fault-tolerant technology has been widely used in all aspects of computer systems as a key mechanism to ensure system reliability. The seL4 microkernel as the world's first complete, formal, machinechecked operating system kernel, has become one of the ideal platforms for safety-critical systems, but the lack of faulttolerant mechanism reduces its reliability and availability. This paper designs and implements a fault-tolerant backup and recovery mechanism based on checkpoint in the seL4 microkernel and makes the optimization of resource. The experiment demonstrates the performance of the backup and recovery mechanism in terms of time and space.
