Service oriented modeling of communication infrastructure for assurance
Albin Zuccato, Bertrand Marquet, Serge Papillon, M. Aldén · 2006
object types as observed and unobserved assurance-releva nt infrastructure items or metrics. In addit ion, the model defines informa tioll relevant for the aggregation of assurance , to allow an assurance value for a service to be derived from its under lying infrastructure. Our modeling approach starts from a service-oriented flow model and stepwise refines the topol ogy and hierarchy view of the infrastructure involved in the service. To validate our approach we model a Voice-over-IP service and show how the approach satisfies initially stated requirements.
