PROCESSOR REDUNDANCY IN A DISTRIBUTED SYSTEM

摘要

A method of automatically recover from multiple permanent failures of processors in a distributed processor system, in particular a software driven telecommunication system. The method involves the creation of an initial configuration describing each processor and software objects executing thereon, and, for each processor the creation of a catastrophe plan to be followed if the processor has a failure. A catastrophe plan contains information as how to redistribute the software objects executing on the faulty processor to operating processor of the processor system. If a processor goes down its software objects are transferred to operating processors following the catastrophe plan for the faulty processor. A hardware and a software model of the processor system and its software is presented. A software object that has a hardware dependency is handled by the model.
