The main focus of this paper is the modeling of a highly reliable real-time distributed system using the RTO.k model incorporated with the monitor approach. The RTO.k model is used to specify the real-time distributed nature of the system while the monitor is to support reliable operations of the system. A monitor is an abstracted software component to handle faults occurred during system operation. It can be modeled as an RTO.k object, called a real-time monitor object (RTMO). In this paper, we present three basic structuring schemes with an RTO.k object and an RTMO. Our modeling approach utilizes these structuring schemes. To illustrate our approach, KODAS being developed at the LG Industrial Systems Co., Ltd., is used. In order to examine the effectiveness of our approach, we have designed the simulation model for KODAS and implemented it on the DREAM kernel. The RTO.k model and the monitor approach can be well incorporated, and can be integrated as a set of RTO.k objects so as to facilitate the modeling of a highly reliable real-time distributed system.
