Abstract
The often neglected problem in the service availability analysis is mapping between ICT-infrastructure and service-level availability. We present an approach which allows to map ICT-infrastructure elements to services, and to analytically assess steady-state, interval and user-perceived service availability, based on failure distributions of ICT-elements that implement a composite service. In case that full topology or all failure distributions of ICT-infrastructure elements are unknown, we provide means to estimate upper and lower availability bounds.
