Middleware for Distributed Industrial Real-Time Systems on ATM Networks

In this paper we address the problem of middleware design for constructing ATM LAN based distributed industrial plant monitoring and control systems. In particular, we present a real-time clientserver programming model based on a uniform ATM network. This model is being realized in our middleware called MidART. The middleware provides a set of industrial application speci c but network transparent programming abstractions and application programming interface API that support individual application QoS requirements. In order to achieve ondemand transmission of plant data, we have developed a concept called selective real-time channels to be supported by MidART. We present the design and protocols of selective real-time channels and describe how QoS requirements of applications are guaranteed.
