Abstract

Object and component technologies play an ever-increasing role in the development of real-time distributed applications. These systems are characterized by the fact that the temporal compatibility of the different objects that are brought together is a condition for success. In this paper, we propose an approach to validate the interoperability of object interfaces with respect to their temporal properties. This approach is based on a recent execution-time calculation technique dedicated to concurrent environments. In this article, we propose a simpler computation framework for this technique, based on Petri nets and J.Y. Girard's (1987, 1990, 1995) linear logic, and we show how it can quite advantageously be adapted to distributed real-time object-oriented systems.
