Real-Time Fault Tolerance Support Middleware", IEEE Workshop on Middleware for Distributed
Real-Time Systems and Services, San Francisco CA, December, 1997
Middleware implementation of various critical services, required by large-scale
and complex real-time applications on top of COTS operating systems, has the tremendous
advantage of reducing the complexity of the design and implementation by separating
the concerns of the application designer for the application functionality from
the concerns for application-independent system issues. In addition, such a middleware
must preferably be structured in an object-oriented fashion owing to the modularity
and natural abstraction benefits object-orientation brings in. This paper presents
the results of a research effort on the development of the Real-time Object-oriented
Adaptive Fault Tolerance Support(ROAFTS) middleware on top of a COTS operating systems,
Solaris, and a COTS CORBA-complaint ORB, Orbix. The supported real-time application
consists of a network of Time-triggered Message-triggered Objects(TMO), the TMO
being a major extension of a conventional object for use in real-time applications.
