REPLICATED OBJECT SOFTWARE SYSTEM UTILIZING DYNAMIC MESSAGING, ESPECIALLY FOR A REDUNDANT ARCHITECTURE CONTROL/COMMAND FACILITY

摘要

Replicated object software system for controlling a redundant architecture control/command facility comprising at least one first processor (1) and a second processor (1'). The software system (2) comprises software objects (3) communicating with one another by messages through a dynamic object messaging mechanism. A replication (2') of the software system (2) is located in the second processor (1'). A number of objects (3) of the software system (2) are marked and the dynamic object messaging (5) further includes control means (51) for identifying an object message intended for a marked object and 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 messaging system (5') in the second processor (1') activates the replication (3') of the marked object (3). The invention is used for implementing a semi-active redundancy method.
