“…However from the technical point of view, Intserv presents difficulties of implementation and deployment in wide area networks [12,13]. The Diffserv model has been designed to ensure end-to-end QoS in large networks [16,17]. DiffServ group of the IETF has defmed three classes of behavior (PHB) for packet processing: Expedited Forwarding (EF): This behavior refer � to the streams transfer with strong temporal constramts such as telephony and video [18].…”

Evaluation of software quality in mobile environments is a subject of active research and is a difficult task. This is caused by dynamic characteristics of mobile networks and the limited resources of mobile devices. This paper presents a study to help quality managers and evaluators using the ISO 9126 software quality standard, with the DiffServ QoS model to evaluate product quality in mobile environments. The effects of mobile technologies limitations are analyzed for each QoS parameter and for each Diffserv class. As a result of this study, the reliability and the efficiency are the software product quality characteristics, the most correlated with Diffserv classes in terms of influence of the mobile environment limitations. It is caused by the fact that these characteristics are dependent on the software runtime environment and the Diffserv QoS model focuses on the quality at the network level, unlike the ISO 9126 standard that applies to the application level.
