✦ Synopsis
Even though real-time systems have the stringent constraint of completing tasks before their deadlines, many existing real-time operating systems do not implement fault tolerance capabilities. In this paper we summarize fault tolerant real-time scheduling policy for dynamic tasks with ready times and deadlines. Our focus in this paper is the implementation, which includes fault-tolerant scheduling, re-scheduling, and recovery mechanisms in the FT-RT-Mach operating system, a fault-tolerant version of RT-Mach. A realtime train control application is then implemented using the FT-RT-Mach operating system.
