The inability of a system or system component to
perform a required function within specified limits. A failure may be
produced when a fault is encountered. [FOLDOC] Service Failure occurs when the delivered service deviates from its correct behavior, determined by its specification or SLA, so it implies that at least one external state of the system deviated from the correct service state. That deviation which led to the observed failure is called an error, while the cause of an error is called a fault. [Pernici & Rosati, 2007] It describes the way in which a service can fail. That is, whether it will halt indefinitely, restart in a well defined initialState, or restart rolledBack to a previous checkpoint. [CD-JRA-1.3.2] {GEN: Network- and Infrastructure-Related Quality} |
