Architecture of ROAFTS/Solaris: A Solaris-Based Middleware for Real-Time Object-Oriented Adaptive Fault Tolerance Support

Middleware implementation of various critical services required by large-scale and complex real-time applications on top of COTS operating system is currently an approach of growing interests. Its main goal is to enable significant reduction in the complexity of application system design and implementation by separating the concerns of the application designer for the application functionality from the concerns for application-independent system issues. This paper presents the middleware architecture named the Realtime Object-oriented Adaptive Fault Tolerance Support (ROAFTS) and a prototype implementation ROAFTS/Solaris realized on top of both a COTS operating systems, Solaris, and a COTS CORBAcomplaint ORB, Orbix. ROAFTS supports distributed real-time applications, each structured as a network of Time-triggered Message-triggered Objects (TMO's), and the TMO is a major extension of a conventional object for use in hard real-time applications. The major components of ROAFTS inclu...
