Unique challenges are present when one tries to build distributed real-time applications using standard o -the-shelf systems which are in common use but are not necessarily designed speci cally for real-time systems. In particular, to realize end-to-end predictability when, say, a process on one node sends data to a process on another node, several issues(More)
In this paper, we propose and present Real-Time Channel-based Reflective Memory (RT-CRM) – a new programming model and middleware communication service for constructing distributed real-time applications on commercially available open systems. RT-CRM provides remote realtime data reflection abstraction IEEE Transactions on Computers, Vol. 49, No. 11,(More)
In this paper, we propose and present Real-Time Channel-based Re ective Memory (RT-CRM) { a useful programming model and middleware communication service for constructing distributed real-time industrial monitoring and control applications on commercially available open systems. RT-CRM provides remote real-time data re ection abstraction using a simple(More)
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(More)
We propose a method for a schedulability check in ATM networks which provide fixed prioritized virtual connections. Our method does not need any run-time scheduling other than fixed priority scheduling at each output link of all switch nodes and traflc shaping at each output link of all terminal nodes in a network. Rate monotonic analysis assumes a critical(More)
In industrial environments such as power plants, automated factories, sewage treatment facilities, railways, etc., digital audio and video play at least three important roles:– • On-line documentation and training. Pre-stored video in documentation databases is typically viewed interactively, both during routine operation and during emergency situations. •(More)
