Abstract
The development of dependable distributed systems needs to be based on a proper foundation. This foundation is generally given in form of a system and failure model. The system model defines the semantics of basic services like process and message services of a distributed system. More advanced system services will be based on these basic services. The failure model specifies the likely failures of the basic services, i.e., these are the failures that the advanced system services need to cope with.
The objective of the system and failure model is the following. As long as the assumptions of the failure and system model are valid, a system has to guarantee its specification. However, if these assumptions are violated during run-time, the system specification might be violated. The probability that a dependable system violates its specification must be negligible. Therefore, the probability of the occurrence of failures which are not specified by the failure model must also be negligible.
