A dynamic of directing service used an object-oriented software system, particularly for a control - / control - a device for a redundant architecture

摘要

The invention relates to a replicated object software system which makes it possible to control a command/control installation, with redundant architecture, comprising at least one first processor (1) and a second processor (1'). The software system (2) comprises software objects (3) communicating with each other by messages via a dynamic-object message service mechanism. A replica (2') of the software system (2) resides in the second processor (1'). Certain objects (3) of the software system (2) are marked and the dynamic object message service (5) further includes a command means (51) for identifying an object message intended for a marked object and a means (52) for passing the contents of the object message, in the form of a network message, to the second processor (1'). In response to the network message, the dynamic object message service (5') in the second processor (1') activates the replica (3') of the marked object (3). The invention makes it possible to implement a semi-active redundancy technique. IMAGE
