The quality of a service is determined by the performance and the resilience of the service and depends on the underlying system (for example the subnetwork) characteristics. These characteristics represent the constraints under which a service provider must provide the requested user quality of service (QoS). To evaluate a quality of a service, an analysis of the service is required to determine a set of QoS parameters from which appropriate metrics for their evaluation are derived. This paper studies the QoS verification issue. A two-level QoS verification is proposed. At the first level a simulation technique is applied to the service specification to predict the quality of service (QoS validation) and at the second level a measurement technique is applied to the service implementation to verify its conformity to the specification from the QoS point of view (QoS testing). A methodological approach to generate QoS test scenarios, as input to QoS verification, is presented. Joint viewing and tele-operating service (JVTOS) telepointer service is taken as a case study to apply our proposals.
