摘要

Conventional distributed processor systems comprise a multitude of processor units in which a standard protocol for safety-relevant processes has to implemented separately by each interface partner. This can lead to errors in the signal chain. The aim of the invention is thus to improve the reliability of such systems and to offer the advantages of a fixed protocol frame, system-wide definition of behaviour in case of a job protocol violation and robust software, i.e. easy maintenance and high test efficiency. According to the invention the processor units (8-24) comprise first and second means for receiving and processing messages. The first means are part of the application program and the second means are application-independent and equally present in all processor units. The method provided for by the invention consists of the processing of a received message in an application-independent manner which is the same for all processor units. The invention is used in telecommunications, notably switching centres and in particular ATM systems.
