Estimation of a domino effect in a loosely coupled distributed system

From the analysis presented it is evident that the setting of only basic points at the input to the new block in a backward recovery scheme for a loosely coupled system has a domino effect as a consequence. That is why it is necessary to generate additional control points such as branch points. To prevent the domino effect it is necessary to suppose additionally that the process is responsible for its negative test. That means that doubt is forbidden except in well-controlled situations
