In this paper we investigate various options for modeling real-time network communication in an existing industrial component model, the rubus component model (RCM). RCM is used to develop resource-constrained real-time and embedded systems in many domains, especially automotive. Our goal is to extend RCM for the development of distributed embedded and real-time systems that employ real-time networks for communication among nodes (processors). The aim of exploring modeling options is to develop generic component types for RCM capable of modeling real-time networks used in the industry today. The selection of new component types is based on many factors including compliance with the industrial modeling standards, compatibility with the existing modeling objects in RCM, capability of modeling legacy systems and legacy communications, ability to model and specify timing related information (properties, requirements and constraints), ease of implementation and automatic generation of new components, and ability of the modeled application to render itself to early timing analysis. © 2011 Springer Science+Business Media B.V.
