METHOD AND DEVICE FOR THE FAULT TOLERANCE MANAGEMENT OF A SOFTWARE COMPONENT

摘要

The invention relates to a method for the fault tolerance management of a software component, said method comprising the following steps: a plurality of entities of the software components is run in at least partially different execution environments, a local susceptibility to interference register and a global susceptibility to interference register being associated with each software component; an interference affecting the operation of a first entity of the software component is detected; the local susceptibility to interference register of the first entity is updated according to the detected fault and the content of the local susceptibility to interference register of the first entity; the global susceptibility to interference register of each entity is updated according to the detected fault and the content of the global susceptibility to interference register of each entity; a difference between each local susceptibility to interference register and each global susceptibility to interference register is determined; and a fault tolerance value of the software component in the respective execution environment is determined according to the difference determined.
