Abstract

Widely distributed systems are constructed step-by-step over a long time. These systems are obliged critical timing check as a final test of newly added or modified real-time application programs in real environment. We propose an autonomous decentralized on-line test technique for verifying distributed and real-time control application programs. It enables testing during system operation without disturbing the operation. And it takes into consideration the difference of timing in on-line subsystems and test subsystem for the more precise verification. We apply the proposed technique to a validation tool for real distributed train traffic control systems and show its effectiveness.
