Abstract
PURPOSE:To avoid the interruption of the overall processing of a device caused by a system switching action by using a switch deciding means which decide whether a device including a faulty processor should be switched to a spare device or not by reference to the information on importance and in accordance with the degree of importance. CONSTITUTION:A decentralized processing system is obtained by duplexing a device which consists of plural processors 10-14 and 20-24 and performs the decentralized processing. In this system the information showing the degrees of importance of the processors 10-14 and 20-24 forming a 0-system packet exchange device 1 and a 1-system packet exchange device 2 respectively are previously stored. When either one of those processors 10-14 and 20-24 has a fault, the switch is carried out between both devices 1 and 2 only when it is decided that the faulty processor contains an important function by reference to the information on the importance of the relevant processor. Thus it is possible to avoid the interruption of the decentralized processing of a system as a whole when a processor containing no important function has a fault.
