Abstract :
Recent papers propose QoS solutions allowing the users to explicitly specify the quality level they request during a so-called explicit QoS service invocation that includes dynamic QoS offering and new mechanisms for authentication, authorization and accounting. In particular, organizations should be able to control their network services and authorize QoS services based on service parameters, as destination addresses, applications and employeespsila roles. Therefore, user profile-based authorization policies for explicit QoS service invocations should be adopted. Each user profile indicates the services that the user is authorized to request, their consumption limits and scope. This paper deals with the authorization of explicit QoS services invocations and proposes a user profile model for profile-based authorization of QoS services.
