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 client-server programming model based on a uniform ATM network. This model is being realized in our mid-dleware called MidART. The middleware provides a set of industrial(More)
Unique challenges are present when one tries to build distributed r eal-time applications using standard oo-the-shelf systems which are i n c ommon use but are not necessarily designed speciically 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(More)
In this paper, we propose and present Real-Time Channel-based Reeective 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 reeection abstraction using a simple(More)
In this paper, we describe our experience in the implementation of MidART { Middleware and network Architecture for distributed Real-Time systems. Our MidART project addresses the problem of middleware design to support high speed network based distributed real-time applications. The uniqueness of MidART lies in the simplicity of services provided and the(More)
This is a position paper discussing the requirements of networks in industrial environments, especially with respect to digital audio and video. Topics include resource allocation, issues surrounding switching, scheduling, and priorities, end system interface requirements, and traffic characteristics and their implications on flow control. This work may not(More)
Unique challenges are present when one tries to build distributed real-time applications using standard off-the-shelf systems which are in common use but are not necessarily designed specifically 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)
