An O-O communication subsystem for real-time distributed Mach

Abstract

Our new communication subsystem for Mach has offered us the opportunity to integrate object oriented programming, real time and fault management. Starting with the Mach operating system and an object oriented protocol development toolkit, based on University of Arizona's x-kernel, we have designed and implemented real time and fault isolation capabilities. The flexibility and extensibility of the object oriented toolkit support us in an evolutionary path towards hard real time, fault tolerance and group communication.
