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 real‐time train control application is then implemented using the FT‐RT‐Mach operating system. Copyright © 1999 John Wiley & Sons, Ltd.
