Application and Network QoS Mapping Using an Ontology-Based Approach

Ideally, during network service negotiation, the QoS specification should be done using user-perceived, application or network parameters. However, this flexibility requires efficient QoS mapping mechanisms. Moreover, the service negotiation using service and application dependent parameters is complex because it applies to a range of services to be negotiated and each service can use different QoS parameters and metrics. Despite this flexibility, a general model must be able to support the automated processing of QoS specifications. Based on the Semantic Web Services technology, this paper proposes an application and network QoS mapping using an Ontology-based approach during service negotiation. The use of our proposal is illustrated to support a VoIP service negotiation.
