Abstract

In various operations related to Quality of Service (QoS) management is necessary to specify the levels of quality through QoS parameters. Most of the works on QoS adopt a fixed set of QoS parameters at the network level. In many situations where humans are the applications/services end-users, ideally the quality of network services should be specified using Quality of Experience (QoE) parameters. However, the adoption of QoE parameters to specify the network QoS requires efficient mechanisms on QoE mapping into network QoS parameters. This paper proposes a QoE and QoS mapping using an Ontology based approach that can be used during various operations related with QoS management. The use of our proposal is illustrated to support a Voice over IP service negotiation.
