Applications classification and QoS requirements

The applications and network services are key points that could provide the user the necessary quality of service. It is very hard to definitely divide the applications and the underlying services to uniquely describe the application and the service classes. This paper tries to comprise different classes of applications into a unique classification. Different standpoints and criteria are included and evaluated The QoS requirements for every defined application class are defined and described. Finally, on the basis of the introduced classification the required service classes for serving such classes are defined.
